Tumor regression grade (TRG) for gastric cancer and radiological methods on predicting response to perioperative chemotherapy: a narrative review

Mainardi, study Mainardi, Campanelli; Collection and data: Garbarino, Mainardi, Polici; Data Background and Objective: Perioperative chemotherapy has been increasingly practiced on gastric cancer (GC) in Western Countries where two third of the patients have locally advanced disease at diagnosis. The histological and radiological evaluation of the tumor response to chemotherapy are both cornerstones of this multimodal therapy to predict the oncological outcomes. This article aims to review the current tumor regression grade (TRG) classification systems available and give an overview regarding radiological methods on predicting response to therapy. Methods: A literature search was performed in MEDLINE (PubMed) and Scopus. The terms tumor regression grade, pathologic response, gastric cancer, gastric adenocarcinoma, RECIST 1.1, radiological prediction of response, perioperative, preoperative and neoadjuvant chemotherapy were included. English papers published until December 2021 were reviewed. Key Content and Findings: Several TRG systems (Dworak, Mandard, Ryan, Becker, and Japanese Gastric Cancer Association-TRG) are available in literature, but none has been widely accepted and indicated by the international guidelines for GC. The response evaluation criteria in solid tumors (RECIST) 1.1 are still the most widely used radiological criteria in clinical trials despite their limitations regarding GC. In fact, the stomach is not a solid organ and its lesions are often not measurables. In order to discriminate responders from non-responders patients to perioperative chemotherapy for GC, all imaging techniques have been evaluated in terms of prediction of tumor response to chemotherapy. there is still no clear evidence of superiority of one imaging the Conclusions: An effective histopathological evaluation method of TRG with an independent for GC in practice.
Energy resilience in buildings for hot tropical climate conditions: A review

Buildings allow satisfying several needs of society, although their construction and use imply significant energy consumption and pollutant emissions. In general, they experience temporary or permanent events that could affect the conditions of well-being, safety, and use of equipment in interior spaces from an energy perspective. It is expected that the building can respond to such events by its design features (passive response) or by its systems (active response), which is studied from the energy resilience approach. However, there is little research on this topic. Therefore, this paper conducts a literature review covering definitions, assessment strategies, and case studies, particularly for the tropical zone, to identify and socialize the most relevant findings to facilitate future research.
Iridium-Functionalized Cellulose Microcrystals as a Novel Luminescent Biomaterial for Biocomposites

Microcrystalline cellulose (MCC) is an emerging material with outstanding properties in many scientific and industrial fields, in particular as an additive in composite materials. Its surface modification allows for the fine-tuning of its properties and the exploitation of these materials in a plethora of applications. In this paper, we present the covalent linkage of a luminescent Ir-complex onto the surface of MCC, representing the first incorporation of an organometallic luminescent probe in this biomaterial. This goal has been achieved with an easy and sustainable procedure, which employs a Bronsted-acid ionic liquid as a catalyst for the esterification reaction of -OH cellulose surface groups. The obtained luminescent cellulose microcrystals display high and stable emissions with the incorporation of only a small amount of iridium (III). Incorporation of MCC-Ir in dry and wet matrices, such as films and gels, has been also demonstrated, showing the maintenance of the luminescent properties even in possible final manufacturers.
A Homological Approach to Factorization

Mott noted a one-to-one correspondence between saturated multiplicatively closed subsets of a domain D and directed convex subgroups of the group of divisibility D. With this, we construct a functor between inclusions into saturated localizations of D and projections onto partially ordered quotient groups of G(D). We use this functor to construct many cochain complexes of o-homomorphisms of po-groups. These complexes naturally lead to some fundamental structure theorems and some natural homology theory that provide insight into the factorization behavior of D.

Mathematical Explanations of a Paradox Observed in a HVAC (High Voltage Alternating Current) Untransposed Overhead Line

The constructive asymmetry of the untransposed overhead lines of a high voltage alternating current is the cause of a great number of difficulties in their operation and modeling. In order to model the operating regimes of such lines, the symmetrical component method, based on constructive symmetry and thus the symmetry of the equivalent phase parameters, is inappropriate, which is why many research papers have been dedicated to either setting up improved modeling methods or to returning to phase coordinate modeling. This paper intends to justify a paradox found on some untransposed overhead lines of a high voltage alternating current during the no-load operating conditions by performing phase coordinate modeling. In such a situation, the transmission or distribution operators measured significant negative values for the active powers on one or two phases at the beginning of the lines. Considering the case of a real untransposed overhead line operating under no-load conditions, the paper starts from presenting the recorded electrical values. Then, the paper moves on to outlining the Carson’s simplified computing relations for calculating the series and shunt primitive equivalent parameters and Kron’s transformation relationships for calculating the phase equivalent parameters. After applying them to the real line, the calculation of the power flow for the no-load operating conditions, which is applied to an equivalent scheme of the line consisting of nine identical octopoles, is performed. Both the untransposed line and its transposed variant are studied here. The values of the electrical amounts obtained by the calculation for the untransposed line are basically similar to those obtained by measuring on the real line, which gives a mathematical confirmation of the so-called paradox. Its occurrence represents the effect of the asymmetry of the equivalent phase capacities, which causes a redistribution of the active powers between the phases of the network to which the overhead line operating in no-load conditions is connected.
Maternal Filicide: A Review of Psychological and External Demographic Risk Factors

ABSTRACT Filicide is an extreme form of homicide defined as the murder of a child at the hand of their parent. Women who kill are often portrayed in the media as angry, psychopathic, vengeful murderers, and their own experiences are often not included. Understanding filicide is complex; it is a mix of both social and psychological factors. This article focuses on a review of literature from 1961–2020. We also review a classification model which identifies filicidal motives including altruistic, acutely psychotic, unwanted child, accidental, and spouse revenge. Characteristics of filicide victims, including age and gender will also be discussed. Additionally, characteristics of maternal perpetrators, including marital status, education level, feelings of rejection, and exposure to neglect or substance abuse will be explored. This paper also reviews psychological risk factors associated with filicide through highlighting differences between psychotic and non-psychotic female perpetrators Lastly, prevention of filicide, including a focus on providing education of risk factors and appropriate language in order to avoid miscommunication and oversight will be explored.
Two implementations of 120 GHz transformer cross‐coupled oscillator based on cascode structure in 55 nm CMOS technology

Two oscillators are designed and fabricated, focusing on the output power and tuning range in the terahertz band. The first one is a transformer cross‐coupled oscillator based on the cascode structure, and the second one is a self‐mixing transformer cross‐coupled oscillator. Higher output power is obtained by using transformer coupling instead of direct or capacitive coupling. Using the frequency mixing principle, a wider tuning range is obtained. Both chips are processed by 55 nm CMOS technology. The measured frequency tuning range is 115.9–129.1 and 110.8–128.0 GHz, respectively. The measured peak value of output power is 3.2 and −14.3 dBm, respectively.
Interpersonal emotion regulation questionnaire: psychometric properties of the Italian version and associations with psychopathology

The emerging field of interpersonal emotion regulation (IER) is drawing attention to forms of emotion regulation which involve communication and social interaction as part of the regulation process. The availability of instruments to measure IER in different languages represents significant promise for future work in this field. The goal of the present study was to validate an Italian adaptation of a self-report instrument for the assessment of IER, the Interpersonal Emotion Regulation Questionnaire (IERQ; Hofmann et al., 2016). In an Italian sample (N=448), exploratory and confirmatory factor analyses confirmed the original structure comprising four factors (Enhancing Positive Affect, Perspective Taking, Soothing and Social Modelling). Correlations with other measures of emotion regulation showed good convergent validity of the questionnaire.

Poverty, Household Structure and Consumption of Foods Away from Home in Peru in 2019: A Cross-Sectional Study

The aim of this study was to evaluate the probability of buying food away from home according to the type of household using the logit model, as well as the sociodemographic characteristics of the heads of household, and how much income expenditure represents. A cross-sectional study was carried out using the National Household Survey (ENAHO) 2019 database. After joining the database, the household type variables were created. To calculate the probability with the “logit” model of purchase, the variables—family size, income, types of household, and total expenditure—were selected as a measure of the purchasing power of the family. A statistically significant association (p < 0.05) was found between the probability of consumption and the variables: age of household members, predominance, nuclear without children–married, nuclear with children–cohabitant, nuclear with children–widowed, nuclear with children–separated, extended, compounded, poor not extreme, and not poor. The bulk of families was represented by nuclear families (61.97%). The highest expenditure in the CFAH was for families defined as composite with a yearly average of USD 1652.89 (equivalent to PEN 5520.67). Observing the expenditure on food consumed outside the home through the composition of households can allow a better approach to offer educational measures. This information can be helpful to developers of educational issues.
New insights into Xenopus sex chromosome genomics from the Marsabit clawed frog X. borealis

In many groups, sex chromosomes change frequently but the drivers of their rapid evolution are varied and often poorly characterized. With an aim of further understanding sex chromosome turnover, we investigated the polymorphic sex chromosomes of the Marsabit clawed frog, Xenopus borealis, using genomic data and a new chromosome‐scale genome assembly. We confirmed previous findings that 54.1 Mb of chromosome 8L is sex‐linked in animals from east Kenya and a laboratory strain, but most (or all) of this region is not sex‐linked in natural populations from west Kenya. Previous work suggests possible degeneration of the Z chromosomes in the east population because many sex‐linked transcripts of this female heterogametic population have female‐biased expression, and we therefore expected this chromosome to not be present in the west population. In contrast, our simulations support a model where most or all of the sex‐linked portion of the Z chromosome from the east acquired autosomal segregation in the west, and where much genetic variation specific to the large sex‐linked portion of the W chromosome from the east is not present in the west. These recent changes are consistent with the hot‐potato model, wherein sex chromosome turnover is favoured by natural selection if it purges a (minimally) degenerate sex‐specific sex chromosome, but counterintuitively suggest natural selection failed to purge a Z chromosome that has signs of more advanced and possibly more ancient regulatory degeneration. These findings highlight complex evolutionary dynamics of young, rapidly evolving Xenopus sex chromosomes and set the stage for mechanistic work aimed at pinpointing additional sex‐determining genes in this group.
Gravitational waveform of moving source with high speed

Current gravitational waveform models used by detection data analysis have not included the effect of the moving speed of the sources relative to detector. Few works about the gravitational waveform problem for moving sources exist in the literature. And all of them have taken some approximations. Some of them just considered frequency shift. Some of them used slow speed approximation. In the current paper, we apply the precise Lorentz transformation of gravitational wave to generate the gravitational waveform for moving sources with any high speed. Our calculation is straightforward but without any approximation. That is to say our result is valid in the whole velocity range 0 ⩽ v < c which is only limited by the speed of light coming from general relativity itself. If only a waveform model of a rest source is given, our result can be applied directly to generate the waveform for the corresponding moving source with any high speed. Such waveform is valid for binary black hole coalescence happening extremely close to a super-massive black hole. As an example, we apply our method to the effect of kick velocity of binary black hole. The adjusted waveform by the kick velocity is presented in the current paper.
Ultrahigh-Speed Optical Interconnects With Thin Film Lithium Niobate Modulator

The exponential growth in data-driven applications like artificial intelligence and metaverse poses an increasing demand for integrated optical interconnects with efficient and cost-effective high-capacity solutions. For short-reach optical interconnects dominated by intensity-modulated direct detection (IM-DD), high-speed and large-capacity transmission enabled by high-bandwidth electro-optic devices is always highly desired. In this article, based on a thin film lithium niobate (TFLN) modulator with a 3-dB bandwidth larger than 110 GHz fabricated by ourselves, we experimentally demonstrate ultrahigh-speed optical interconnects with probabilistic shaping pulse amplitude modulation (PS-PAM) signals. With linear pre-equalization and Volterra nonlinear equalizer (VNLE), a 120 Gbaud PS-PAM16 signal with a bit rate up to 408 Gb/s is generated. Compared to the regular-PAM8 signal with the same bit rate of 360Gb/s, the PS-PAM signal demonstrates a receiver sensitivity gain of 2.2 dB. With the help of VNLE, 384.5 Gb/s PS-PAM16 signal can be transmitted over 500 m standard single-mode fiber (SSMF) at the C band. The ultra-broadband TFLN enabled transmission provides a promising solution for future 400G per wavelength data-center interconnects.
Use of multilayer recursive model for non-linear dynamic system identification

Abstract In practice, the dynamics of the system are uncertain due to nonlinear and dynamic characteristics. It is difficult to establish accurate identification and prediction of the nonlinear plants that require dynamic modelling of the system. Extreme learning machine (ELM) as the recursive model due to its fast training and convergence speed is utilized in this work. However, its limitation is that it has only 1 hidden neuron which tends to make evolution speed low. Further, Multi-layer ELM (ML-ELM) model is applied on a nonlinear Auto-regressive complex benchmark system. The performance of ML-ELM is compared with dynamic recurrent functional link neural network (DRFLNN), functional link neural network (FLNN), nonlinear auto-regressive moving average (NARAX), multi-layer perception (MLP), radial basis function network (RBFN), Elman recurrent neural network (ERNN), and basic ELM models. From the comparison table, it can be seen that ML-ELM has better performance as compared with other models.
Multilevel inverter with active clamping diodes for energy efficiency improvement

Multilevel inverters can replace commonly used two-level inverters for three-phase electrical drives. In this lowvoltage range new wide-bandgap power switches (SiC MOSFET, GaN FET) are available. In the four-, five- and sevenlevel inverters, the majority of the power losses are caused by the threshold voltage of the clamping diodes. The new idea is the replacement of the clamping diodes by active switches, since they only have low on-resistance in the forward direction. In this case freewheeling paths of the clamping diodes would have to be actively switched. However, the control signals for the clamping switches can be generated by logic operations from the control signals for the main switches. The use of active clamping switches has significant potential to reduce semiconductor losses, but requires the development of wide-bandgap power semiconductors with reverse blocking capability. At nominal motor operation point of the 5.5 kW induction motor a loss reduction of 56 % between active clamping switches and clamping diodes is possible. With a higher number of inverter levels, the size of the motor filter can be reduced by about 70 % and also the losses can be reduced by 73 %.
Abscesso cerebral: manifestações clínicas e diagnóstico com abordagem radiológica

O abscesso cerebral é uma lesão expansiva e possui a maior parte das suas manifestações derivadas desse efeito de massa sobre o parênquima encefálico. Essa apresentação geralmente é constituída pela tríade: cefaleia, febre e déficits neurológicos focais, porém, as literaturas atuais instituem que essa relação tem maior especificidade do que sensibilidade, visto que a maior parte dos pacientes não apresenta a tríade ao diagnóstico. Nesse direcionamento, é visto que a alteração do estado mental é de maior coerência ao efeito expansivo da lesão, sendo considerada uma associação de maior representatividade do abscesso cerebral. Nessa medida, são realizadas técnicas de neuroimagem em pacientes que apresentam quadros infecciosos agudos ou crônicos originados das possíveis fontes de contaminação, associados a uma sintomatologia com convulsões, déficits neurológicos focais ou sinais de aumento da pressão intracraniana. Dessa forma, o diagnóstico neurorradiológico distingue a lesão que se apresenta como uma hipodensidade na TC, hipointensidade na RMT1 e hiperintensidade na RMT2 e FLAIR, associada com uma borda de realce, característica do abscesso cerebral e importante no diagnóstico diferencial.
A Simplified Predictive Current Control of Open-End Winding Permanent Magnet Synchronous Motor

Model predictive current control (MPCC) of a 4-level inversion fed open-end winding permanent magnet synchronous motor (OEW-PMSM) using 37 voltage vectors (VV) suffers from the disadvantage of the increased computation burden. A high computation burden on the processor puts a limit on the selection of the minimum sampling time. In this article, a novel method is presented for reducing the computation burden. The proposed method reduces the number of candidate VVs from 37 to a maximum of 4 and a simple cost function is proposed to select the optimal VV. The proposed method calculates the change in stator current (CSC) needed to obtain the required change in the stator flux. The CSC vector is in the direction of the required change in the stator flux, which is used to shortlist the candidate VV for the reduced control set. The required change in the flux is obtained using the reference stator current of the next sample. The multiple predictions of the d-q currents are eliminated and a simple cost function based on the difference between per-unit CSC and candidate VV is used to simplify the calculations. The proposed method is experimentally tested and compared with existing MPCC. The results confirm the effectiveness of the proposed scheme.
The Role of Moringa Leaf Extract as a Plant Biostimulant in Improving the Quality of Agricultural Products

Ensuring high-quality agricultural products has become important in agriculture since society’s standard of living has risen. Meanwhile, Moringa oleifera L. leaf extract (MLE) has been used as a plant biostimulant to improve product quality. The effectiveness of MLE is associated with its beneficial components, consisting of nutrients, phytohormones, secondary metabolites, amino acids, and bioactive compounds. Previous studies have been carried out to find the effects of MLE application on the quality of different crops, including basil, kale, spinach, maize, radish, brinjal, pepper, tomato, grape, strawberry, and more. The results are generally positive concerning physical, nutritional, and chemical qualities. This review comprises recent findings regarding MLE application as a plant biostimulant to increase quality attributes, with its underlying mechanism.
