Left lateral occipito-temporal cortex encodes compatibility between hands and tools: an fMRI adaptation study

Previous work has demonstrated that a region of the extrastriate visual cortex, the left lateral occipito-temporal cortex, contains a region that is activated by both images of human hands and manual tools. The current paper examined the functional significance of this observation. A functional Magnetic Resonance Imaging (fMRI) adaptation paradigm was used to investigate the hypothesis that this region is selective for the functional compatibility of hands and tools. The present results suggest that this region is indeed involved in matching compatible hands postures with tools for their skilled and effective use, with significant adaptation with successive presentation of compatible hands and tools. It is proposed that this region of the extrastriate visual cortex represents a crucial node within a much wider cortical network that supports skilled tool use in humans. The present results are discussed in terms of their implication for our understanding of the organization of the visual brain.
Empirical Evidence on the Economic Impacts of Hotel Taxes

Tourist taxes are an important source of revenue for many governments. In the United States, all states impose them in the form of hotel/motel occupancy taxes, yet there is little ex post evidence as to whether such taxes affect occupancy rates. This study uses a precise establishment-level data source to examine California's varying rates by city, enabling powerful tests. The author finds that such taxes have negligible impacts on hotel sales and employment. On the other hand, hotels/motels operating in higher tax-rate cities tended to have more financial stress in terms of lower Dun and Bradstreet credit ratings.
Hidden trauma: Men’s non-disclosure of female perpetrated partner violence in selected communities of Limpopo Province

Purpose of the study: The current study was aimed at exploring men’s non-disclosure of intimate partner violence at Sekhukhune District in Limpopo Province, South Africa. Methodology: Qualitative research methodology and exploratory research design were applied to successfully explore heterosexual men’s non-disclosure of intimate partner violence. A non-probability sampling of blended convenience sampling and snowball sampling was employed. Data was collected using a semi-structured interview guide with open-ended questions and was analysed through thematic analysis of qualitative data. Main findings: This study found that male victims of partner violence hide their situations. Determinants of non-disclosure were found to include men’s personal feelings of fear to disclose, masculinity factors, societal expectations, and cultural norms, which negatively affect men’s decisions to disclose. Avoidance of possible harm and judgement from others appeared to influence non-disclosure. Novelty/originality of the study: The findings of the study raise concern for lack of knowledge on violence against men. Social services professionals can use the findings to advocate for male victims’ rights and use the same resources aimed at helping female victims to provide protection and psychosocial assistance to male victims. The public needs to be made aware that women are not the only victims of IPV and as such be educated about the vulnerability of male victims.
Composites of poly[4-((p-tolylimino)methyl)phenyl acrylate] and the Ni-complex with aminated MWCNT: Thermal, electrical and magnetic investigation

Abstract Its nickel complex and a polyacrylate with side chain the Schiff base obtained from the condensation reaction of 4-hydroxybenzaldehide and p-toluidine, have been synthesized. The three-component composites were prepared using the polyacrylate, poly[4-((p-tolylimino) methyl) phenyl acrylate], its Ni-complex, and aminated MWCNT at three different percent (2%, 8% and 15% by wt). For characterization, FT-IR, 1H-NMR, SEM-EDX, SEM images and VSM (vibrating sample magnetometer) were used. The specific magnetic susceptibility for the Ni-complex is calculated as 3.0 × 10−8 m3/kg from the slope of VSM straight line and the Ni-complex shows paramagnetic property. Thermal stabilities of the composites decreased compared with the polymer and Ni-complex. The AC conductivities of the samples increased with increasing frequency and increasing temperature. Frequency exponent of the equation connecting the AC conductivity to angular frequency was calculated as between 1.06 and 0.86 at 298 K and between 0.97 and 0.71 at 320 K, for all samples. Log σac vs 1000/T straight lines were generated above and below the Tg temperature and the activation energies were calculated from the slopes as the values between 0.097 and 0.331 eV below Tg and the values between 1.134 and 0.768 eV above Tg.
Empirical Analysis of Stock Systemic Risk and Idiosyncratic Risk Pricing Capability—Comparison of Conditional and Unconditional CAPM

This paper proposed the view that idiosyncratic risk pricing ability may come from systemic risk pricing ability spillover, and studies the relationship of pricing ability between systemic risk and idiosyncratic risk of stock, based on the conditional and unconditional CAPM, by using the method of two-stage Fama-MacBeth regression. From the results of cross-sectional regression, adding idiosyncratic risk could increase the risk explanatory power of earnings, and the idiosyncratic volatility has a significant positive risk premium. However, with the improvement of the CAPM, the marginal contribution of the idiosyncratic risk to improve the explanatory ability has declined. In addition, this paper compares Fama-French double-packet portfolios and the time-delay factors of conditional CAPM, and finds that the time-lag factor of conditional CAPM has a high correlation with the size and BM of the portfolio. This means that small-size or low-value stock may have a more significant time lag effect.
Enzyme-linked immunosorbent assay for aflatoxin B1 using a portable pH meter as the readout

The pH meter, one of the most common sensors for laboratory measurements, has the advantages of excellent sensitivity, low price, high reliability, and ease of use. In this study, the high sensitivity of the pH meter was coupled with the high selectivity of immunosorbent assay to develop a simple and portable biosensor for aflatoxin B1 (AFB1) determination. Urease was first labelled on the AFB1 antigen, in the presence of AFB1; the target competed with the urease-labeled AFB1 antigen to be captured by the antibody. Urease could catalyse the hydrolysis of urea into ammonia and induce the pH increase of the solution; the change could easily be detected using a handheld pH meter or pH-sensitive dye. Under optimized conditions, the pH value enhancement had a linear relationship with the logarithm of the concentration of AFB1 in the range of 0.62 to 23.42 ng mL−1. The proposed biosensor has been applied to detect AFB1 in real samples with satisfactory results.
Tailoring Crystal Structure of FA0.83Cs0.17PbI3 Perovskite Through Guanidinium Doping for Enhanced Performance and Tunable Hysteresis of Planar Perovskite Solar Cells

Current–voltage hysteresis of perovskite solar cells (PSCs) has raised the concern of accurate performance measurement in practice. Although various theories have been proposed to elucidate this phenomenon, the origin of hysteresis is still an open question. Herein, the use of guanidinium cation (Gu+)‐dopant is demonstrated to tailor the crystal structure of mixed‐cation formamidinium‐cesium lead triiodide (FA0.83Cs0.17PbI3) perovskite, resulting in an improved energy conversion efficiency and tunable current–voltage hysteresis characteristic in planar solar cells. Particularly, when the concentration of Gu‐dopant for the perovskite film increases, the normal hysteresis initially observed in the pristine PSC is first suppressed with 2%‐Gu‐dopant, then changed to inverted hysteresis with a higher Gu‐dopant. The hysteresis tunability behavior is attributed to the interplay of charge/ion accumulation and recombination at interfaces in the PSC. Furthermore, compared to the cell without Gu+‐dopant, the optimal content of 2% Gu+‐dopant also increases the device efficiency by 14%, reaching over 17% under one sun illumination.
Clonal hematopoiesis detection in cancer patients using cell free DNA sequencing

In the context of cancer, clonal hematopoiesis of indeterminate potential (CHIP) is associated with the development of therapy-related myeloid neoplasms and shorter overall survival. Cell-free DNA (cfDNA) sequencing is becoming widely adopted for genomic screening of cancer patients but has not been used extensively to determine CHIP status due to a requirement for matched blood and tumor sequencing. Here we present an accurate machine learning approach to determine clonal hematopoiesis (CH) status from cfDNA sequencing alone and apply our model to 4,096 oncology clinical cfDNA samples. Using this method, we determine that 26% of patients in this cohort have evidence of CH and CH is most common in lung cancer patients. Matched RNAseq data shows signals of increased inflammation, especially neutrophil activation, within the tumor microenvironment of CH-positive patients. Additionally, CH patients showed evidence of neutrophil activation systemically, pointing to a potential mechanism of action for the worse outcomes associated with CH status. Neutrophil activation may be one of many mechanisms however, as estrogen positive breast cancer patients harboring TET2 frameshift mutations had worse outcomes but similar neutrophil levels to CH-negative patients. One Sentence Summary We train an accurate machine learning model to detect clonal hematopoiesis in cancer and characterize associated changes in the tumor microenvironment.

The increase in the release due to increase in the flux.
Teaching 4.0 Competency in Higher Learning Institutions: A Systematic Mapping Review

Technology 4.0 has forced the education system to undergo a huge transformation by changing teaching and learning methods. Teaching 4.0 requires teachers to apply varieties of technology used in the teaching and learning process to make it more appealing to new millennials. However, the response to this change has been relatively slow. Consequently, the preparation of effective teaching methods and strategies from educators that can benefit students through learning from differentiated learning styles. Thus, the aim of this study is to collect and extract information from the literature in searching for the research gap, and analyse the most significant studies on the teaching of 4.0 competency in a Higher Learning Institution. The searching process will focus on papers published in journals or presented at specialised international conferences from 2015 until 2021 using a systematic mapping review (SMR). A total of 380 relevant research papers from Scopus, Web of Science, Google Scholars online databases and grey literature were retrieved. Nine final papers were selected in the study. Results from the review showed that the predefined requirement criteria for Teaching 4.0 competencies were not all satisfied in literature. There are limited studies on the Teaching 4.0 competency. Thus, a conceptual framework of measurement for Teaching 4.0 competencies should be developed. It could act as a solution by providing a comprehensive competency measurement and to determine relevant 4.0 competency among Higher Learning Institution educators.
Reduced Graphene Oxide/TiO2 Nanocomposite: From Synthesis to Characterization for Efficient Visible Light Photocatalytic Applications

In this study, a green and facile thermal reduction of graphene oxide using an eco-friendly system of d-(+)-glucose and NH4OH for the preparation of reduced graphene oxide was described. The obtained reduced graphene oxide dispersion was characterized by SEM, Dynamic Light Scattering, Raman and X-Ray Photoelectron Spectroscopy. TiO2 nanoparticles and reduced graphene oxide nanocomposites were successively prepared and used in the preparation of heterogeneous photocatalysts that were characterized by Atomic Force Microscopy and Photoluminescence Spectroscopy and subsequently tested as visible light photocatalysts for the photodegradation of Alizarin Red S in water as target pollutant. Obtained results of photocatalytic tests regarding the visible light photocatalytic degradation of Alizarin Red S demonstrated that the use of reduced graphene oxide in combination with TiO2 led to a significant improvement for both adsorption of Alizarin Red S on the catalyst surface and photodegradation efficiencies when compared to those obtained with not doped TiO2.
Study on photoelectric properties of surface tio2 nanoparticles doped with sn4+ ion

This paper prepares pure TiO2 nanoparticles and TiO2 nanoparticles doped with different tin contents using sol-gel method, characterizes the structure of the samples using XRD, UV-Vis and surface photovoltage spectroscopy (SPS), analyzes the effects of annealing temperature and Sn4+ doping amount on the surface photoelectric properties of TiO2 nanoparticles, and discusses the mechanism of the effect of Sn4+ doping on the surface photoelectric properties of TiO2 nanoparticles. The experimental results show that the tin ion doping can significantly increase the surface photovoltage of the TiO2 nanoparticles, while 3 mol% is the optimal doping concentration for tin ion.
Artifacts in EEG-Based BCI Therapies: Friend or Foe?

EEG-based brain-computer interfaces (BCI) have promising therapeutic potential beyond traditional neurofeedback training, such as enabling personalized and optimized virtual reality (VR) neurorehabilitation paradigms where the timing and parameters of the visual experience is synchronized with specific brain-states. While BCI algorithms are often designed to focus on whichever portion of a signal is most informative, in these brain-state-synchronized applications, it is of critical importance that the resulting decoder is sensitive to physiological brain activity representative of various mental states, and not to artifacts such as those arising from naturalistic movements. In this study, we compare the relative classification accuracy with which different motor tasks can be decoded from both extracted brain activity and artifacts contained in the EEG signal. EEG data was collected from 17 chronic stroke patients while performing six different head, hand, and arm movements in a realistic VR-based neurorehabilitation paradigm. Results show that the artifact component of the EEG signal is significantly more informative than brain activity to the classifier. This finding is consistent across different feature extraction methods and classification pipelines. Whereas informative artifacts are a helpful friend in BCI-based communication applications, they can be a problematic foe in the estimation of physiological brain states.
Impact of Proton and Electron Irradiation-Induced Defects on the Dark Current of GaAs Solar Cells

The same amount of non-ionizing energy is deposited in GaAs solar cells through 1 MeV proton and electron radiation at specific fluence values. The defects created are detected and characterized via temperature-dependent dark I–V analysis, and the energy levels are correlated to trap states observed via admittance spectroscopy. A remarkable difference is observed between the defect energy levels introduced in the proton and electron cases: in the former, the recombination centers lie around the mid-gap position, while in the latter they are spread over a wider energy range in the band-gap. This induces a profound difference in the degradation of the recombination current in the space-charge region. On the other hand, the degradation of the diffusion current in the neutral regions is found to be determined by the recombination velocities at the back and front hetero-interfaces of the solar cell. They depend only on the displacement damage dose and are independent of the particle type.
A Polarization-Reconfigurable Metasurface Antenna

A metasurface antenna with left-handed circularly polarized (LHCP) and right-handed circularly polarized (RHCP) polarization reconfigurability performance is proposed in this paper. The simulated results manifest that the impedance bandwidth less than −10dB and the 3dB axial ratio (AR) bandwidth are 3.59GHz~4.04GHz (11.8%) and 3.58GHz~4.11GHz (13.8%), respectively. The peak gains of both the dual CP states are 7.8 dBi.
Assassination Tango: An NLR/NLR-ID immune receptors pair of rapeseed co-operates inside the nucleus to activate cell death

Plant immunity relies on cell-surface receptors and intracellular NLR immune receptors. Some plant NLRs carry integrated domains (IDs) that that mimic authentic pathogens effector targets. We report here the identification in Brassica napus of the genetically linked NLR/NLR-ID pair, BnRPR1 and BnRPR2. The NLR-ID carries two ID fusions and their mode of action conforms to the proposed “integrated sensor/decoy” model. The two NLRs interact and the heterocomplex localizes in the plant-cell nucleus and nucleolus. However, the BnRPRs pair does not operate through a negative regulation as it was previously reported for other NLR-IDs. Cell death is induced only upon co-expression of the two proteins and it is dependent on the helper genes EDS1 and NRG1. Truncations of the IDs of BnRPR1 results in cytoplasmic localization and compromises cell death activation. Expression, using the native promoter in Nicotiana species, led to a conditional cell death induction. However, this was not the case for the transgenic Arabidopsis, where no cell death was observed. In summary, we describe a new pair of NLR-IDs with interesting features in relation to its regulation and the cell death activation.
Granular cell tumors overexpress TFE3 without gene rearrangement: Evaluation of immunohistochemistry and break-apart FISH in 45 cases

Transcription factor E3 (TFE3) is a useful marker for tumors with Xp11.2 translocation, including alveolar soft part sarcoma and renal cell carcinoma. Recently, TFE3 overexpression was also found in granular cell tumors (GrCTs). However, the case cohorts of these two studies were limited to only 11 and 6 cases. Whether aberrant TFE3 expression is a common feature of Asian patients with GrCT requires further investigation. In the present study, immunohistochemical staining and TFE3 break-apart fluorescence in situ hybridization (FISH) assay were performed in 45 samples of GrCTs obtained from Chinese patients recruited from three medical centers in northeast China. Diffusive and marked nuclear staining for TFE3 was identified in 11/45 (24%) cases, which was lower than previously reported. Focal or weak TFE3 staining was identified in 13/45 (29%) cases. The remaining 21 cases were negative stained. In addition, GrCTs in subcutaneous tissue exhibited a relatively higher ratio (8/45, 18%) for TFE3 expression, compared with those in other sites. Furthermore, according to FISH data, no rearrangement or amplification of TFE3 was identified in these cases, whether they were positively or negatively stained for TFE3. The results from the present study demonstrated that part of patients GrCTs exhibited TFE3 overexpression, which suggested that this may not be derived from gene rearrangement.
A Review of Battery State of Health Estimation*

Batteries as energy storage instruments are widely used in electric vehicles, uninterrupted power supply (UPS), communications and random fluctuations. The state of health (SOH) for batteries has a significant impact on traffic safety, communication reliability and energy efficiency. The performance of batteries is affected by the aging of batteries with the increase of service time. Due to the interaction of various factors, and the battery is a highly coupled, complex mechanism, non-linear parameter change system, the characterization of battery aging phenomenon is very complex. In this paper, the existing SOH estimation methods for batteries are reviewed and classified in different fields.

Guards and Watchdogs in One-Way Synchronization with Delay-Related Authentication Mechanisms

In this paper, we consider ways of using secondary “Watchdog” mechanisms to protect primary time synchronization protocols from single-source or single-channel errors. This approach is particularly interesting when the Watchdog mechanism has stronger cryptographic protection than the primary synchronization mechanism. We specifically discuss the case where the primary mechanism employs one-way communication and is secured with an authentication scheme based on delayed disclosure of cryptographic information. Further, we present results from experiments with an implementation combining such a primary mechanism with a secured two-way control mechanism, which lead us to overall recommend the approach.
