The aversiveness of intrusiveness: Evidence from involuntary musical imagery
Authors: Akerman‐Nathan Aviv , Naftalovich Hadar , Kalanthroff Eyal 
Published: September 2023

AbstractObjectiveIntrusive thoughts are characterized by a sense of intrusiveness of foreign entry into cognition. While not always consisting of negative content, intrusive thoughts are almost solely investigated in that context. Involuntary Musical Imagery (INMI) offers a promising alternative, as it is a type of involuntary cognition that can be used to evaluate intrusiveness without negative content.MethodsIn Study 1, 200 participants completed self‐report questionnaires to assess several aspects of intrusiveness: meta‐awareness, control, repetitiveness, frequency, and subjective experience of INMI. In Study 2, 203 participants completed self‐report questionnaires to explore the clinical characteristics (depression, stress, anxiety, and rumination) which might mediate the connection between INMI frequency and INMI negative experience.ResultsStudy 1 revealed, through exploratory factor analysis, that intrusiveness shares variance with the negative experience of INMI but not with INMI frequency. In Study 2, ruminative thinking was found to mediate the relationship between frequent INMI and the negative experience of INMI.ConclusionThese results suggest that INMI might be used to investigate intrusiveness in the lab without the potential confound of negative emotions. In addition, the results suggest that neither the content nor the frequency of intrusive thoughts can solely explain why these thoughts are aversive to some but not others. Ruminative style might be the missing link to explain how and why these intrusive thoughts become aversive and obsessive. In other words, we suggest that the cause for intrusiveness lies not in the thought or repetitiveness, but in the thinker.
Loneliness and sense of community are not two sides of the same coin: Identifying different determinants using the 2019 Nova Scotia Quality of Life data

Published: September 2023

AbstractThe purpose of this study was to explore the relative importance of lifestyle factors and living conditions when predicting loneliness and sense of community (SOC) in a representative sample of 12,871 participants from Nova Scotia collected in 2019. Using multiple regression and measures of relative importance based on the Lindeman, Merenda and Gold (lmg) method, we identified which variables are most important to predicting measures of loneliness and SOC. Twenty‐two predictors accounted for 46% of the variance in SOC and the top 10 predictors accounted for 36% of the variance: satisfaction with quality of the natural environment in the neighborhood (ri = 0.09), life satisfaction (ri = 0.05), number of neighbors one can rely on (ri = 0.05), confidence in institutions (ri = 0.05), feeling better off due to government policy or programming (ri = 0.04), feeling safe walking in neighborhood after dark (ri = 0.03), mental health (ri = 0.02), number of friends one can rely on (ri = 0.02), volunteering (ri = 0.02), and perceptions of time adequacy (ri = 0.02). Only six of these variables were also the top predictors of loneliness. These results show that both community‐ and individual‐level variables are substantial predictors of social well‐being. The effect sizes differ between models, which suggests that there may be important predictors of loneliness that we have not accounted for. This study may inform community‐level programming and policy that seeks to promote social well‐being for individuals and their communities.

In this study, 15 different carbohydrate sources (white raw rice, red raw rice, white basmati rice, red basmati rice, wheat, atta flour, soy, black gram, corn, finger millet, water lily seeds, kithul, chickpea, oats, and palmyra sprouts) in Sri Lanka were investigated for their physicochemical and functional properties.ResultsThe shape of the extracted starch granules varied according to the source, and the amylose content ranged from 17.22% to 36.12%. Kithul and black gram showed the highest water swelling capacity and water absorption index, respectively. Flour of white raw rice and finger millet showed significantly higher (p < 0.05) freeze–thaw stability than other sources. Flour of Soy, black gram, and chickpea showed significantly higher (p < 0.05) dietary fiber content and potassium content than other samples. Water lily seeds showed remarkable in vitro prebiotic activity from the studied carbohydrate sources.ConclusionThe study indicates the potential utilization of raw white rice, palmyra, and finger millet starch in the food processing industry as alternatives to conventional starch sources. Furthermore, the flour from water lily seeds, white basmati rice, soy, and black gram has the potential for use in functional food preparation, offering a wide range of health benefits.

AbstractBACKGROUND60Co‐γ irradiation can simulate the effects of aging and enhance the flavor of distilled spirits. The present study aimed to investigate the effects of 0, 2, 4, 6, 8 and 10 kGy 60Co‐γ irradiation doses on the key aroma components in newly produced navel orange distilled spirits and thus determine the mechanism of their aging distilled spirits.RESULTSThe identification of aroma compounds demonstrated that ethyl hexanoate, d‐limonene, ethyl octanoate, 3‐methyl‐1‐butanol and linalool are the key aroma compounds in navel orange distilled spirits, which were increased except for linalool with irradiation doses of 2–6 kGy. Irradiation treatment simulated the effects of the aging of navel orange distilled spirits by promoting the content of total acids, total esters and aldehydes. Irradiation doses of 2–6 kGy increased the aroma intensity of navel orange distilled spirits, reaching an optimum at 6 kGy. However, irradiation doses as high as 8 and 10 kGy decreased the content of esters in navel orange distilled spirits, which led to a deterioration of the spirit flavor.CONCLUSIONLow doses of 60Co‐γ irradiation can simulate the effects of the aging by increasing the content of key aromatic compounds in navel orange distilled spirits. © 2023 Society of Chemical Industry.

AbstractBackgroundType 2 diabetes mellitus (T2DM) is a prevalent metabolic disease that poses significant health risks due to its numerous complications. However, the effects of eumelanin on oxidative stress, hyperglycemia and depression in diabetic mice have not been extensively studied.ResultsOur study employed an enzymatic approach to extract eumelanin from squid ink and characterized it using spectroscopic techniques. Remarkably, eumelanin extracted with alkaline‐neutral‐flavor protease (ANF) displayed superior inhibitory activity against α‐glucosidase and α‐amylase, while enhancing glucose utilization and hepatic glycogen synthesis in human hepatocellular carcinoma cell line (HepG2) insulin resistance model. Further evaluation of ANF in a T2DM ICR mouse model demonstrated its significant potential in alleviating hyperglycemia, reducing glycosylated serum protein levels, improving glucose tolerance and modulating total cholesterol and low‐density lipoprotein levels, as well as antioxidant indices at a dosage of 0.04 g kg−1. Additionally, ANF exhibited positive effects on energy levels and reduced immobility time in antidepressant behavioral experiments. Moreover, ANF positively influenced the density and infiltration state of renal cells, while mitigating inflammatory enlargement and deformation of liver cells, without inducing any adverse effects in mice.ConclusionOverall, these findings underscore the significant therapeutic potential of ANF in the treatment of T2DM and its associated complications. By augmenting lipid and glucose metabolism, mitigating oxidative stress and alleviating depression, ANF emerges as a promising candidate for multifaceted intervention. © 2023 Society of Chemical Industry.

Published: September 2023

AbstractHerein, an evaluation of the initial step of benzoxazine polymerization is presented by mass spectrometry, with a focus on differentiating the phenoxy and phenolic products formed by distinct pathways of the cationic ring opening polymerization (ROP) mechanism of polybenzoxazine formation. The use of infrared multiple photon dissociation (IRMPD) and ion mobility spectrometry (IMS) techniques allows for differentiation of the two pathways and provides valuable insights into the ROP mechanism. The results suggest that type I pathway is favored in the initial stages of the reaction yielding the phenoxy product, while type II product should be observed at later stages when the phenoxy product would interconvert to the most stable type II phenolic product. Overall, the findings presented here provide important information on the initial step of the benzoxazine polymerization, allowing the development of optimal polymerization conditions and represents a way to evaluate other multifunctional polymerization processes.

Published: September 2023

AbstractAgeing is inevitable and poses a universal challenge for all living organisms, including humans. The human body experiences rapid cell division and metabolism until approximately 25 years of age, after which the accumulation of metabolic by‐products and cellular damage leads to age‐related diseases. Neurodegenerative diseases are of concern due to their irreversible nature, lack of effective treatment, and impact on society and the economy. Researchers are interested in finding drugs that can effectively alleviate ageing and age‐related diseases without side‐effects. Psychobiotics are a novel class of probiotic organisms and prebiotic interventions that confer mental health benefits to the host when taken appropriately. Psychobiotic strains affect functions related to the central nervous system (CNS) and behaviors mediated by the Gut‐Brain‐Axis (GBA) through various pathways. There is an increasing interest in researchers of these microbial‐based psychopharmaceuticals. Psychobiotics have been reported to reduce neuronal ageing, inflammation, oxidative stress, and cortisol levels; increase synaptic plasticity and levels of neurotransmitters and antioxidants. The present review focuses on the manifestation of elderly neurodegenerative and mental disorders, particularly Alzheimer's disease (AD), Parkinson's disease (PD), and depression, and the current status of their potential alleviation through psychobiotic interventions, highlighting their possible mechanisms of action.

AbstractP‐substrate AlGaInAs/InP lasers are enabled using an internal carbon‐doped layer to block Zn‐diffusion. These inverted lasers are developed for the aim of further monolithic vertical integration with passive or active material, which would allow full system on‐chip integration. The lasers emit at 1.5
μm making them ideal for telecommunication applications. Different p‐substrate laser designs were grown to quantify the effect the carbon doped layer had on blocking Zn p‐dopants diffusion, which permits the long growths necessary for vertical integration. Current, voltage, and capacitance measurements were used to examine the different laser designs, proving that Zn p‐dopant diffusion is responsible for p‐substrate laser failure.

Published: September 2023

AbstractA novel compact tri‐band multiple‐input multiple‐output (MIMO) antenna element based on composite right/left‐handed transmission line (CRLH‐TL) for the fifth‐generation (5G) mobile handsets is presented. First, by using the coupled‐fed loop with the CRLH‐TL zeroth‐order resonator (ZOR) structure, we propose a compact antenna element covering 1.525/3.45/4.9 GHz bands (1490‐1560/3300‐3600/ 4800‐5000 MHz). A band‐stop matching circuit (BSMC) is also added between the feeding point and the element to expand the 1.525 GHz band to 1490‐1710 MHz. Then, an MIMO array with eight proposed tri‐band elements is designed and fabricated. The measured results show that the MIMO array operates in 1.6/3.45/4.9 GHz bands (1490‐1710/3300‐3600/4800‐5000 MHz) with good isolations (more than 10 dB) and acceptable radiation efficiencies. Furthermore, the envelop correlation coefficients (ECCs) between any two elements in the MIMO array are less than 0.23.

AbstractThe printed inverted F antenna (PIFA) has been developed in various shapes for the wireless application. In this paper, we have developed a novel shape based on loop antenna where it is in interaction with the split ring resonator (SRR) load and the extended ground by two vias for multi‐band antenna to cover, GSM900, GSM1800, UMTS, GSM1900, WCDMA 100, 802.11b/g, LTE2600, and 802.11a/n. The antenna total dimensions are 100 mm × 60 mm and it is fabricated on a low‐cost FR‐4 substrate. The prototype antenna has omnidirectional pattern and VSWR is lower than 3 for wireless requested frequency. We obtained 2‐4 dBi antenna gain plus 70% efficiency and circular polarization at 2.5 and 5.5 GHz. The prototype antenna shows low SAR for GSM 900 and GSM 1800 while it has checked for 1 g and 10 g with maximum value of 0.942 and 1.27 W/kg for 900 and 1800 MHz, respectively. In this new survey, the SAR value is decreased sensitively as per previous range in PIFA. The prototype has simulated with HFSS and CST that we used full wave method in both simulation software and finally we compared simulation and experimental result.

Published: September 2023

AbstractA wideband Wilkinson power divider using parallel LC resonant circuit is proposed for different phase output differences. The design theory of the wideband power divider is derived by making the difference between the slopes of the added line for phase shift and the slopes of parallel LC resonant circuit constant zero, and then, the formula is used to find the value L and C. For easy fabrication, the lumped element L and C are implemented as the shunt stub of distributed element.The proposed circuit on Rogers RT 5880 is designed and measured to verify the new design concept. For accurate comparison, the phase shift line of the conventional Wilkinson power divider is added to one of output ports, and the proposed circuit is fabricated with 45° and 90° power divider at 1.5 GHz central frequency. The fractional bandwidth of the proposed 45° and 90° power divider in case of ±10° phase deviation is over 120% and 100%, respectively. Therefore, the measured results are in good agreement with the design method, and the proposed one will be much smaller size than 90° or 180° hybrid couplers. The proposed Wilkin‐ son power divider will be applicable for phase shifter and various microwave circuits.

Published: September 2023

AbstractA compact branch‐line hybrid coupler with harmonic suppression based on slow‐wave microstrip lines is presented in this paper. These slow‐wave artificial transmission lines are implemented by simultaneously loading a host line with series inductors and shunt capacitors. By this means, the effective capacitance and inductance of the line are increased and, consequently, the phase velocity and signal wavelength are reduced. This slow‐wave effect, useful for device miniaturization, is applied to reduce the size of the coupler. Particularly, by implementing the reactive elements through capacitive patches and inductive strips, 64% size reduction, as compared to the conventional coupler, is achieved. Moreover, due to the filtering capability of the inductors and capacitors, the first and second harmonic responses of the coupler are completely suppressed. A detailed design methodology based on the schematic of the proposed slow‐wave transmission line is reported. The work includes a simple analysis to justify that two unit cells per transmission line section are necessary to suppress the harmonic bands leaving unaltered the coupler response in the region of interest. The fabricated device is fully planar, does not use vias, and the ground plane is kept unaltered.

Published: September 2023

AbstractA new passive compensation structure for Chebyshev‐I complex band‐pass filter is presented. The proposed method aims to cancel the excess phase lag of the integrators caused by the limited gain‐bandwidth product (GBW) of the amplifier, thus ensuring the in‐band flatness of the magnitude‐frequency response. A fifth‐order Chebyshev‐I active‐RC complex band‐pass filter (CBPF) is implemented in TSMC 0.13 μm CMOS technology with a center frequency of 12.24 MHz and a bandwidth of 9 MHz for low‐IF receivers. The CBPF achieves a 46 dB image rejection ratio, a 0.7 dB ripple in the passband and consumes 14.6 mA current from a 1.5 V power supply.

Published: September 2023

AbstractA new wideband 0.18‐μm SiGe BiCMOS power amplifier (PA) operating from 16.5 to 25.5 GHz is presented. The PA consists of a drive amplifier and two main amplifiers integrated through lumped‐element Wilkinson power divider and combiner. The PA exploits the advantages of both HBT and NMOS characteristics in a cascode topology in addition to floating the NMOS body to achieve good gain, output power, power‐aided efficiency (PAE), and linearity. The developed PA has relatively flat saturated output power (Psat) of 18.5‐20.8 dBm, output 1‐dB compression point (OP1dB) of 15.1‐18.1 dBm, 13.5‐23% maximum PAE, and gain of 19.5 ±1.5 dB across 16.5‐25.5 GHz. At 24 GHz, the PA achieves Psat, OP1dB, maximum PAE, and gain of 20.8 dBm, 18.1 dBm, 23%, and 20 dB, respectively.

AbstractIn this letter, a highly miniaturizedal‐band frequency selective surface (FSS) is designed and experimentally verified. The proposed structure has orthogonally meandered metallic strips with an opening at one point in the loop. This single sided FSS operates at 1.23 and 3.3 GHz with a compact unit cell size dimension of 0.033λ0 × 0.033λ0 × 0.003λ0 where λ0 stands for the free space wavelength at the lower resonating frequency. Parametric and circuit analyses of the formulated structure has been carried out to have a comprehensive understanding of the model. The structure has stable resonance for TE and TM polarizations at various incident angles. The presented FSS is fabricated and measured. A good similitude between the simulation and measurement has been obtained.

Published: September 2023

AbstractA wideband antenna using metasurface is proposed for the future 5G communications. By using the metasurface and the multi‐layer substrate with high relative permittivity, the height of the proposed antenna can be reduced to 0.11 𝛌c in the operating frequency band. The metasurface including 40 unit cells are arranged on the second layer to improve the gain at the upper frequencies. Besides, by employing the dual arc‐shaped defected ground structure, the impedance bandwidth can also be broaden and the gain can be improved. The measured result shows that an impedance bandwidth of 77.2% (1.63‐3.68 GHz) with a stable gain of 5.1 ± 1.2 dBi can be obtained. Hence, the proposed antenna is potentially suitable for the future 5G communications.
