Assessment of Cognition in Hypertensives and Normotensives: A Comparative P300 Study

Background: Hypertension is an established risk factor for dementia, and the prevalence of hypertension and dementia is rising. Current tests to diagnose cognitive dysfunction at an early stage lack sensitivity and specificity. Recently event-related potentials (ERPs) have gained much attention in diagnosing cognitive dysfunction and are independent of the education status of the subject. This study was done to find any cognitive deficits in the hypertensive population with electrophysiological evidence, which might open the doors for the need to screen the population at an earlier stage so that the population can be prevented from dementia. Methods: Some 31 middle-aged (18-65 years) hypertensives were compared with 31 age, sex, education, and handedness matched normotensives about cognition by neuropsychometric test battery including Hindi Mini-mental Status Examination (HMSE), Hindi Montreal Cognitive Assessment (MoCA), choice reaction time (CRT), and auditory event-related potentials. Results: Hypertensives and normotensives differed significantly concerning P300 potentials’ latency (Fz and Cz P300 latencies: p-value: 0.001), and this change was correlated well with the duration of diastolic blood pressure (BP) (r-value: 0.670). The remaining tests, HMSE, Hindi MoCA, and CRT, were dependent on the education status of the patient. Conclusions: The effect of hypertension on cognitive impairment is evident and can be proved early in its pre-clinical stage using ERPs. Early identification can help in specifying high-risk individuals. ERPs have great potential in screening and diagnosing and can also help in assessing cognition as a reliable tool to show the effect of treatments/interventions on cognitive defects.
Reliability assessment of GaN HEMTs on Si substrate with ultra-short gate dedicated to power applications at frequency above 40 GHz

This Ph.D. work focuses on the reliability assessment of ultra-short gate AlGaN/GaN high electron mobility transistor (HEMT) on silicon substrate dedicated to power applications at frequency above 40GHz. It was carried out within IMS Bordeaux and IEMN Lille laboratories.This work initially compares AlGaN/GaN HEMTs grown by MOCVD with those grown using MBE, through electrical characterization.In particular, the device geometry impact on the device performances has been studies by static electrical characterization.Step-stress experiments are performed to investigate reliability assessment of ultra-short gate AlGaN/GaN high electron mobility transistor (HEMT) on Si substrate. A methodology based on a sequence of step stress tests has been defined for in-situ diagnosis of a permanent degradation and of a degradation which is identified by a drain current transient occurring during each step of the ageing sequence . The same stress conditions were applied on HEMTs with different geometries. It is found no evolution of the drain current during non stressful steps. The value of the critical degradation voltage beyond which the stress drain current starts to decrease significantly is also found dependent on the stress bias conditions, the gate-drain distance and the gate length. Moreover, the safe operating area of this technology has been determined.
Facilitating Cyber Security Threat Modelling: A Social Capital Perspective

To identify and manage their cyber security risks, organisations need to form a thorough understanding of various factors that may expose them to these risks. While cyber security professionals and scholars have developed a plethora of practical methodologies and frameworks to support cyber security risk identification and mitigation, the theoretical foundations on what promotes effective knowledge creation when using these methodologies and frameworks are nascent. Yet, theories developed in the field of knowledge management and intellectual capital may provide valuable insight on how to enhance cyber security risk related knowledge creation in organisations. For example, social capital is considered as an important prerequisite for knowledge exchange and combination when creating new intellectual capital (Nahapiet & Ghoshal, 1998). However, more focused research is required to understand how social capital affects knowledge creation in the context of organisational cyber security risk related activities. Using qualitative data gathered from three cyber security threat modelling workshops, this paper examines how social capital enables conditions for exchanging and combining knowledge on cyber security threats. By comparing the empirical observations with Nahapiet and Ghoshal’s (1998) model, this study identifies practical approaches that are used by threat modelling workshop facilitators to create conditions for effective knowledge exchange and combination. This study provides both cyber security scholars and professionals with an example on how to use knowledge creation related academic theories to analyse and further enhance cyber security risk management approaches by creating a connection between Nahapiet and Ghoshal’s (1998) social capital model and cyber security threat modelling.

Earnings, Size, and Book-to-Market Effects on Banking Stock Returns in Nepal

This study attempts to examine the effect of earnings, size, and book-to-market equity on common stock returns of banking sector firms in Nepal. Using the sample of 21 commercial banks in Nepal consisting of 231 firm-year observations over the 2010-2020 periods and based on the panel data fixed-effect estimation with AR(1) disturbances, the study reveals that earnings and size have significant positive effects on common stock returns of the banking sector in Nepal. However, the study reveals significant negative book-to-market equity effects on cross-sectional banking stock returns in Nepal. The positive earnings effect implies that banks with higher earnings yields have higher stock returns. Similarly, the positive size-effect implies that larger banks outperform the smaller banks in Nepal. Similarly, the negative book-to-market effect on common stock returns observed in this study implies that banks with lower value creation have lower stock returns.
The Magnetic Evolution of the Taurus Molecular Cloud

The morphology and kinematics of the dense core regions within the Taurus Molecular Cloud complex are examined from enhanced (C-13)O J = 1-0 emission and are compared with the local direction of the interstellar magnetic field determined from earlier polarization measurements. The core orientations and rotational axes are not systematically aligned with the local magnetic field direction. Rather, the distribution of rotational axes is uniform. Such nonalignment may reflect the inability of the magnetic field to exert a significant stress upon the mostly neutral material at the densities which characterize cloud cores. The existence of significant angular momentum at these moderately high densities and the uniformly distributed axes may imply that the angular momentum problem is not completely resolved by magnetic braking but rather by other processes such as fragmentation of the collapsing core or stellar wind activity. The observed random distribution of core rotational axes may be due to core-core interactions. Thus, these dense core regions may have lifetimes comparable to the core-core collision time scale of 4 million yr. 34 references.
SEC-BADAEC: An Efficient ECC With No Vacancy for Strong Memory Protection

Shrinking process technology and rising memory densities have made memories increasingly vulnerable to errors. Accordingly, DRAM vendors have introduced On-die Error Correction Code (O-ECC) to protect data against the growing number of errors. Current O-ECC provides weak Single Error Correction (SEC), but future memories will require stronger protection as error rates rise. This paper proposes a novel ECC, called Single Error Correction–Byte-Aligned Double Adjacent Error Correction (SEC-BADAEC), and its construction algorithm to improve memory reliability. SEC-BADAEC requires the same redundancy as SEC O-ECC, but it can also correct some frequent 2-bit error patterns. Our evaluation shows SEC-BADAEC can improve memory reliability by 23.5% and system-level reliability by 29.8% with negligible overheads.
Establishment and verification of a nomogram for predicting survival in patients with triple-positive breast cancer

Background Triple-positive breast cancer (TPBC) is a specific type of breast cancer characterized by the positive expression of estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor receptor 2 (HER-2). In recent years, the research on breast cancer has been increasing year by year, but there are few studies on TPBC, especially the lack of analysis with large sample size. In this study, sufficient samples were provided through the SEER database, explore the factors affecting the prognosis of TPBC, and construct a prediction model, in order to assess the individual survival of patients, and help clinicians accurately identify high-risk patients and develop personalized treatment plans. Methods Patients pathologically diagnosed with TPBC were recruited from Surveillance, Epidemiology, and End Results (SEER) database and randomly divided into training and validation groups (7:3 ratio). Univariate analysis was used to analyze the related factors affecting the prognosis of TPBC patients in the modeling group, and then multivariate Cox proportional hazards model was used to analyze the significant factors to screen out the independent risk factors affecting the 3- and 5-year overall survival (OS) rate and construct the prediction model. Using the concordance index (C-index) and calibration curve were performed to evaluate the predictive ability of the model. Results The results of the Cox risk-scale model showed that race, age, marital status, tumor grade, tumor, node, metastasis stage, surgical treatment, chemotherapy, and radiotherapy affected the prognosis of TPBC patients (P<0.05) in the training group, and the factors were used to construct a nomogram. The internal and external validation of the nomogram chart indicated that the C-index of the training group was 0.85 [95% confidence interval (CI): 0.836, 0.863] and that of the verification group was 0.833 (95% CI: 0.807, 0.858). The calibration curves of the 2 groups showed that the OS predicted by the model was consistent with the actual survival of the patients. Conclusions The prediction model accurately predicted the prognosis of and identified high-risk TPBC patients.
One-Pot Electrochemical Synthesis of Lead Oxide- Electrochemically Reduced Graphene Oxide Nanostructures and Their Electrocatalytic Applications

In this paper, a new electrochemical method for the cathodic electrodeposition of lead oxide-electrochemically reduced graphene oxide (PbO-ERGO) from an aqueous solution was carried out in one-pot in the same solution containing Pb<sup>2+</sup> and graphene oxide, leading to the direct formation of crystalline thin films at near-room temperature. XRD was employed to determine the crystallinity index of the PbO-ERGO nanostructures. SEM, XPS, EDS, and UV–visible spectroscopy techniques were employed to analyze the morphological, structural, and optical characteristics of the composite materials. Owing to the rapid charge transport in the composite materials of PbO-ERGO, rapid, and uniform photocurrent responses were observed. In addition, the PbO-ERGO composite electrode exhibited a 40 and 130 fold increase in the photocatalytic performance compared to PbO and ERGO electrodes, respectively. Then, the nanocomposite-modified electrode was applied for the non-enzymatic sensing of H<sub>2</sub>O<sub>2</sub>. A linear amperometric response to H<sub>2</sub>O<sub>2</sub> was observed at concentrations in the range from <inline-formula> <tex-math notation="LaTeX">$1 \times 10^{-5}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$10\times 10^{-3}$ </tex-math></inline-formula> mol L<sup>−1</sup>. The sensitivity and detection limit of the PbO-ERGO electrode were estimated as <inline-formula> <tex-math notation="LaTeX">$2.26~\mu \text{A}$ </tex-math></inline-formula> mM<sup>−1</sup> cm<sup>−2</sup> and <inline-formula> <tex-math notation="LaTeX">$2\times 10^{-7}$ </tex-math></inline-formula> mol L<sup>−1</sup>, respectively, at a signal-to-noise ratio of 3.0.
An analysis of power and conviction around land and linked natural resources in the Western Highlands of Cameroon

Questions on power exercise by natural resource actors and inherent conflicts have gained traction in scientific and policy circles in sub-Saharan Africa (SSA), although there is virtual neglect of harmful convictions embedded in the exercise of power. To bridge this gap, this paper explores power and convictions around land and linked natural resources in Cameroon. Data was generated through focus group discussions (N = 14), key informant (N = 44) and expert interviews (N = 19). The analysis drew from the actor-centered power lens employing thematic and content analysis. The results indicate the following: First, while gender-based and elitism-based harmful convictions significantly shape land and linked natural resource access, region/ethnic-based and religion-based convictions were less significant. Second, actors championing gender-based convictions employ more coercive approaches, while elitist and political actors make use of incentives. This study informs the actor-centered power (ACP) approach, with emphasis on the convictions embedded in the exercise of power during natural resource acquisition.
Design and Simulation Studies of a Continuously Tunable Sub-THz Gyrotron Using Magnetic and Thermal Tuning Schemes

In this article, the frequency tunability of a sub-Terahertz (THz) gyrotron has been investigated using both magnetic and thermal tuning schemes. A triode-type magnetron injection gun (MIG) has been designed using an electron optics tool, which predicted an annular electron beam with a < 4% velocity spread. Furthermore, the cavity has been modeled to operate in the TE11,2 mode at 527 GHz for dynamic nuclear polarization-nuclear magnetic resonance (DNP/NMR) applications. The transient behavior of the present gyrotron has been studied using a time-dependent self-consistent multimode code. A maximum continuous wave (CW) power of ~14 W was obtained at 527.20 GHz with 16.75 kV, 90 mA, and 1.85 pitch of e-beam. The tunable bandwidth has been obtained as ~0.31 GHz (527.20–527.51 GHz) by using a magnetic tuning scheme and ~0.31 GHz (526.90–527.20 GHz) by using the thermal tuning scheme by taking advantage of gyrotron sensitivity on cavity structural parameters and cavity shape.
Double-Inlet Left Ventricle

Double-inlet left ventricle (DILV) is most frequent among univentricular atrioventricular connections. In DILV, there is a single functioning ventricle, most commonly with left ventricular structure. This chamber receives both atrioventricular valves and is connected to an outlet chamber with morphologic features of the right ventricle. The great vessels are often transposed, and pulmonary stenosis is seen in two-thirds of patients. The anatomy and pathophysiology can be defined by echo-Doppler studies with a rare need for other imaging studies. The management is mostly related to the nature of associated heart defects and the degree of pathophysiological abnormality. When the infants present initially, treatment to address the hemodynamic issues is undertaken. Subsequently, these babies need staged total cavo-pulmonary connection, i.e., the Fontan procedure which is undertaken in three stages; these stages are described in this review. The existence of inter-stage mortality and post-Fontan complications is recognized and was reviewed. The paper concludes that DILV can be successfully diagnosed with echo-Doppler studies and this heart anomaly can be effectively treated with the currently prevailing medical, catheter interventional, and surgical treatment practices.
Design and build a mechanical energy conservation law KIT with Arduino microcontroller

Tools as media play an important role in learning physics to explain concepts, so that students can more easily build mastery of physics material and develop their skills. This study aims to design and realize a physics learning tool. The method used is research and development (Research and Development). This learning tool is in the form of a plane where the direction of the object's trajectory varies can move up, down, and is accompanied by a slope setting (30˚, 45˚, 60˚ or 90˚). Equipped with a speed output setting program based on 3 points whose speed will be measured and the distance between the points can be changed. Its function is to understand and prove the law of conservation of mechanical energy, understand the relationship between potential energy and kinetic energy experienced by objects and determine the speed of objects and their height position. This learning tool is expected to attract students' interest in learning physics. The design of this KIT Law of Conservation of Mechanical Energy can prove the conservation of mechanical energy. When an object is moving downwards, the object's height decreases but its velocity increases. On the other hand, if the object is moving upwards, the height of the object will increase, but the velocity of the object will decrease. This tool still has a relative error rate of 23.92% in free fall motion, 31.87% in falling motion on an inclined plane, and 32.79% in vertical upward motion. ©2021 JNSMR UIN Walisongo.

Sulforaphane Regulates eNOS Activation and NO Production via Src-Mediated PI3K/Akt Signaling in Human Endothelial EA.hy926 Cells

Sulforaphane (SFN) is a naturally occurring isothiocyanate that is abundant in many cruciferous vegetables, such as broccoli and cauliflower, and it has been observed to exert numerous biological activities. In the present study, we investigate the effect of SFN on eNOS, a key regulatory enzyme of vascular homeostasis and underlying intracellular pathways, in human endothelial EA.hy926 cells. The results indicate that SFN treatment significantly increases NO production and eNOS phosphorylation in a time- and dose-dependent fashion and also augments Akt phosphorylation in a time- and dose-dependent manner. Meanwhile, pretreatment with LY294002 (a specific PI3K inhibitor) suppresses the phosphorylation of eNOS and NO production. Furthermore, SFN time- and dose-dependently induces the phosphorylation of Src kinase, a further upstream regulator of PI3K, while PP2 pretreatment (a specific Src inhibitor) eliminates the increase in phosphorylated Akt, eNOS and the production of NO derived from eNOS. Overall, the present study uncovers a novel effect of SFN to stimulate eNOS activity in EA.hy926 cells by regulating NO bioavailability. These findings provide clear evidence that SFN regulates eNOS activity and NO bioavailability, suggesting a promising therapeutic candidate to prevent endothelial dysfunction, atherosclerosis and other cardiovascular diseases.
A new frequency estimation method for a real-valued waveform with multiple sub-Nyquist channels based on the ESPRIT algorithm

Real-valued waveform frequency measurement problems are often encountered in signal processing and they can be solved by designing a linear system. However, they require the sampling frequency to reach twice the maximum of the measured frequency, that is, to meet the Nyquist condition, which in many cases cannot be satisfied considering the hardware limitation. Therefore, how to design a nonlinear method to reconstruct the signal frequency is of great significance. To solve the frequency estimation problem for a real-valued waveform with sub-Nyquist channels, we propose a frequency estimator based on multiple sub-Nyquist channels. Our algorithm mainly consists of the following parts: 1) Calculate the folded frequencies which are lying on the first Nyquist region for each channel based on ESPRIT. 2) Reconstruct the signal frequency by a search method according to the set of folded frequencies. Finally, the simulation results verify the good performance of our proposed algorithm.
