A Nonagenarian’s View of Dietary Impacts on Cellular Immunology

Descriptions of immune functions and diets often use oversimplified terms that lead to misunderstandings plus expectations that conflict with reality. “ Unexpected events are a clear marker for the frontier of knowledge and a new opportunity to learn” [1]. Terms like lipid, fluidity, unsaturated, essential, lipoprotein, receptor, immune and inflammatory have many unmentioned components and attributes that may be either causal mediators or associated epiphenomena in heath disorders. Including neglected details can help investigators design dietary interventions with observed consequences that fit their expectations. Over the years, new evidence and explicit terminology allow expected outcomes for interventions to fit reality. A recent review, “ Lipid nutrition: ‘In silico’ studies and undeveloped experiments ” [1], describes some aspects of fatty acid chemistry and nutrition with important consequences on chronic immune-inflammatory processes. The review points to long-known details of lipid-protein interactions which younger colleagues can consider as they develop new experiments to gather evidence on how food choices might prevent healthy physiology from drifting into pathophysiology.

Digital services to improve customer experience. An empirical analysis of the impact of chatbots on customer-brand relationships.

Purpose of the paper : Many firms are investing in digital services in an attempt to improve customer experience. Virtual service agents or "e-service agents" such as chatbots are examples of these efforts. Chatbots are a type of virtual assistant software programs that are able to interact with users through voice or text. This paper aims to investigate whether perceived hedonic and utilitarian attributes of chatbots can influence customer satisfaction and as a consequence the relationship with the brands. Methodology : Data were collected through a questionnaire-based survey among a sample of Italian consumers. A convenience sampling technique was used. Data were then analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM) to provide a prediction-oriented model assessment. Main Findings : The first findings confirm the hypothesis that the perceived hedonic and utilitarian attributes of chatbots positively influence customer satisfaction and improve customer relationships with the brands. Practical implications : This study suggests the importance for firms to invest (also) in the adoption of e-agents to strengthen the consumer–brand relationship. Originality/value : This article tries to enrich and consolidate the growing body of literature about the impacts of new technologies, and specifically chatbots, in service marketing.

, ABSTRACT Logistics is an important driver for the competitiveness of industries and material supply. The development of smart logistics, powered by precise positioning and communication technologies can signiﬁcantly improve the efﬁciency of logistics. The emerging technology of ultra-wideband (UWB) precision positioning has attracted signiﬁcant attention throughout the previous decade owing to its promising capabilities over other radio frequency-based indoor localisation systems. In addition, UWB is characterised by large bandwidth and data rate, short message length, low transmission power and high penetration capability, which are all favourable for indoor positioning applications. However, UWB localisation technology faces several challenges that are somewhat similar to other technologies, such as mitigating errors that originate from non-line-of-sight (NLOS) situations and tackling signal interference in dense environments, and when required to operate in extreme conditions. This paper reviews the most recent advances made in UWB positioning systems over the last ﬁve years, with a focus on high-ranking articles. In addition to going through more conventional solutions to UWB challenges, modern solutions, which involve the use of machine learning and sensor data fusion, are discussed. We highlight the most promising ﬁndings of the recently implemented and foreseen UWB positioning systems by providing a summary of each reviewed article. Additionally, we address a major challenge that faces the UWB positioning technology: NLOS situations, focusing on some proposed remedies such as multi-sensor fusion and machine learning. As an application, this study introduces how UWB technology promotes smart logistics by offering indoor positioning to improve efﬁciencies in the delivery of goods from the source to the customer. Furthermore, it demonstrates the beneﬁts of UWB technology for accurate positioning and tracking of both stationary and moving items, and machinery in an indoor logistics environment.
Document Classification Using Hierarchies Clusters Technique

In this paper we introduce the PHOCS-2 calculation, which removes an "Predicted Hierarchy of Classifiers". The extricated pecking order causes us to improve execution of level arrangement. Hubs in the chain of importance contain classifiers. Each middle hub Corresponds to an arrangement of classes and each leaf hub relates to a solitary class. In the PHOCS-2 we make estimation for every hub and accomplish more exact calculation of false positives, genuine positives and false negatives. Halting criteria depend on the aftereffects of the level characterization. The proposed calculation is approved against nine datasets.

Caulk+: Table-independent lookup arguments

The recent work of Caulk [ZBK + 22] introduces the security notion of position hiding linkability for vector commitment schemes, providing a zero-knowledge argument that a committed vector’s elements comprise a subset of some other committed vector. The protocol has very low cost to the prover in the case where the size m of the subset vector is much smaller than the size n of the one containing it. The asymptotic prover complexity is O ( m 2 + m log n ), where the log n dependence comes from a subprotocol showing that the roots of a blinded polynomial are all n th roots of unity. In this work, we show how to simplify this argument, replacing the subprotocol with a polynomial divisibility check and thereby reducing the asymptotic prover complexity to O ( m 2 ), removing any dependence on n .
AN OVERVIEW OF NEUROLOGICAL DISORDER: EPILEPSY

: Epilepsy is one of the neurological disorder which is typically a unusual changes in electric impulse of brain and it affected millions of people around the world. It may acquire through genetic inheritance or physical head trauma. Basically, epilepsy is identifiable by seizures, generalized and focal seizures are the two types. Which generally initiated by high frequency flare up of the action potential and increased synchronization of neuronal population. This neurological disorder condition is a result of the pathogenesis of various brain environment affecting comorbidity consequences of various disease such as cerebrovascular disease and some seizures can also show the signs of the actual stroke. Antiepileptic drugs may help to reduce the symptoms such as benzodiazepines and it can be diagnosed by impacting identifying procedures such as the EEG (Electroencephalogram) also by neurological examination. A Surgery can help to remove the affected region by a neurosurgeon. This neurological disorder is the most common medical chronic conditions, it seems that in 100,000 population there are almost 50% case appear per year. But almost 80% of epileptic patients controlled by medications. As far as this neurological disorder goes to generations to generations by far some patients can’t able to show some positive response to the actually pharmacological drugs. This neurological disorder condition is not only seems to appear in this modern age it also appeared in the olden ancient days. Some epilepsies appears to be in the form of idiopathic which came to appear around the fourty percentage of the entire people who are affected by this neurological disorder medical condition epilepsy around the world which shows a difficulty joined and combined the part of the Inheritance which is in genes In a straight structure to perform in the another way to the patient who are affected by this neurological disorder medical condition to produce a important pointed systematic syndrome But some types of this neurological disorder condition epilepsy found to be more common in people with the family history.

An Effective Machine Learning-Based Spam Detection Method for IoT Devices

: Millions of devices with sensors and actuators connected via wired or wireless channels for data transmission make up the Internet of Things (IoT). By 2020, it is anticipated that over 25 billion devices will be connected, reflecting the IoT's tremendous growth over the last ten years. In the upcoming years, the amount of data released from these devices will multiply many-fold. In addition to producing more data overall, IoT devices also produce a lot of data in a variety of different modalities, with variable degrees of data quality determined by the speed of time and position dependency. In such a setting, machine learning algorithms can be crucial in assuring biotechnology-based security and authorisation as well as anomaly detection to enhance IoT systems. However, hackers frequently use learning algorithms to attack the flaws in IoT-based smart systems. In this study, we suggest employing machine learning to detect spam in order to secure IoT devices. Spam Detection in IoT utilising a Machine Learning framework is suggested to accomplish this goal. In this approach, a huge number of input feature sets are used to evaluate five machine learning models using a variety of criteria. Each model uses the enhanced input attributes to calculate a spam score. This rating shows how trustworthy Internet of Things (IoT) devices are based on several factors. The proposed technique is validated using the REFIT Smart Home dataset. In comparison to other current systems, the findings collected demonstrate the effectiveness of the proposed method.

Global trade of hydrogen: what is the best way to transfer hydrogen over long distances?

As a manufactured fuel, hydrogen can be produced in a decentralized way in most countries around the world. This means, even in a net zero economy, the global trade of hydrogen could look quite different to the current international trade in fossil fuels, including natural gas. With further declines in the costs of renewable electricity and electrolyzers, regions which have lower cost renewable electricity may develop an economic advantage in the production of low-cost hydrogen, but for hydrogen to become a globally traded commodity, the cost of imports needs to be lower than the cost of domestic production. Unlike oil or natural gas, transporting hydrogen over long distances is not an easy task. Hydrogen liquefaction is an extremely energy-intensive process, while maintaining the low temperature required for long-distance transportation and storage purposes results in additional energy losses and accompanying costs. The upside is that hydrogen can be converted into multiple carriers that have a higher energy density and higher transport capacity and can potentially be cheaper to transport over long distances. Among the substances currently identified as potential hydrogen carriers suitable for marine shipping, liquid ammonia, the so-called ‘liquid organic hydrogen carriers’ in general (toluene-methylcyclohexane (MCH) in particular), and methanol have received the most attention in recent years. This paper compares the key techno-economic characteristics of these potential carriers with that of liquified hydrogen in order to develop a better understanding of the ways in which hydrogen could be transported overseas in an efficient manner. The paper also discusses other factors, beyond techno-economic features, that may affect the choice of optimum hydrogen carrier for long distance transport, as well as the global trade, of hydrogen.
Cancerous phenotypes associated with hypoxia-inducible factors are not influenced by the volatile anesthetic isoflurane in renal cell carcinoma

The possibility that anesthesia during cancer surgery may affect cancer recurrence, metastasis, and patient prognosis has become one of the most important topics of interest in cancer treatment. For example, the volatile anesthetic isoflurane was reported in several studies to induce hypoxia-inducible factors, and thereby enhance malignant phenotypes in vitro. Indeed, these transcription factors are considered critical regulators of cancer-related hallmarks, including “sustained proliferative signaling, evasion of growth suppressors, resistance to cell death, replicative immortality, angiogenesis, invasion, and metastasis. ” This study aimed to investigate the impact of isoflurane on the growth and migration of derivatives of the renal cell line RCC4. We indicated that isoflurane treatment did not positively influence cancer cell phenotypes, and that hypoxia-inducible factors (HIFs) maintain hallmark cancer cell phenotypes including gene expressions signature, metabolism, cell proliferation and cell motility. The present results indicate that HIF activity is not influenced by the volatile anesthetic isoflurane.
Hydrogen shuttling near Hf-defect complexes in Si∕SiO2∕HfO2 structures

We propose that a defect complex comprising a suboxide Hf–Si bond and an interfacial dangling bond is responsible for the stress-induced buildup of interface traps in Si∕SiO2∕HfO2 capacitors. With the aid of first-principles calculations, we show that these defects possess a symmetric double-well energy minimum with a moderate intervening barrier. The calculated activation energies suggest a relatively easy hopping of H atoms between the two energy minima (a field-aided shuttling mechanism). This mechanism can explain the experimentally measured oscillations of interface-trap densities during switched-bias conditions following x-ray irradiation or constant-voltage stress.
Analysis and Design of an Efficient and Wideband Common Collector Class B Amplifier for Auxiliary Envelope Tracking Supply Modulator

— In this paper, an efficient and wideband class B amplifier is designed for the application as a supply modulator of an Envelope Tracking (ET) radio frequency power amplifier (RFPA). The common collector configuration is used to drive a low output impedance as the output signal of this amplifier will be used as the bias signal to the drain port of the RFPA. A quasi-complementary design which is also referred to as a totem-pole with a pair of n-type transistors is implemented to build the class B amplifier. In this design, the transistors are biased properly to avoid cross over distortion and thus maintain a good level of linearity. The wideband property of the amplifier has been achieved by controlling the values of the coupling capacitors. A good efficiency is recorded by using a step-up center tapped transformer at the emitter outputs of the transistors. Simulation results show that if the input AC signal level is chosen to be half of the maximum DC voltage level, then a transformer turn ratio of 1:6 will give an efficiency of 87%. Moreover, the bandwidth is recorded to be almost 80 MHz after using a 10 uF coupling capacitor of 10 uF and a 70 uF bypass capacitor. The proposed supply modulator is suitable for the base station applications of the LTE networks.
