En este trabajo se presenta un método de minimización para el Regularized Phase Tracking empleando la técnica de punto fijo, con la cual se obtiene un error normalizado similar a los métodos de minimización clásicos, pero con una notable reducción del tiempo de procesamiento.
Vida cotidiana y movilidad con perspectiva de género en barrios periféricos con segregación residencial
Authors: Díaz Núñez Verónica Livier , Cireddu Alessandra , Nápoles Franco Diego
Published: June 2023

El crecimiento desordenado en las grandes urbes de América Latina ha traído consigo el incremento de la segregación residencial, sobre todo en barrios periféricos con condiciones estructurales y materiales de pobreza, carentes de equipamiento urbano y servicios públicos básicos, indispensables para el desarrollo de las actividades cotidianas que inciden en la calidad de vida de sus habitantes. A través de un acercamiento metodológico de corte cualitativo, y desde la percepción de las residentes, se analiza la problemática de movilidad presente en el barrio periférico Lomas del Centinela en Zapopan, Jalisco, identificando los principales impactos en la vida cotidiana de las mujeres. En relación con esto, se considera que el déficit o la existencia precaria de equipamientos urbanos y espacios públicos —cuyo acceso se da por medio de calles y banquetas con condiciones físicas inadecuadas— dificulta la movilidad cotidiana e incrementa las condiciones de segregación residencial. Esto impacta de forma negativa en la realización de las actividades y tareas cotidianas básicas de la población que habita estos asentamientos periféricos de las áreas metropolitanas.

Controlled sun exposure can greatly benefit vitamin D synthesis, however, irresponsible sun exposure can cause considerable biological damage. Among the extraterrestrial solar radiation that reaches the earth's surface, UV rays are characterized by having the shortest wavelengths (less than 400 nm) and the highest frequencies, which is why they concentrate a large amount of energy. In particular, radiation with wavelengths less than 300 nm can alter DNA molecules and cause biological damage such as skin changes, cataracts, possible mutations, immunosuppression, photoaging and many other conditions. Therefore, this research estimates the global solar radiation and the incident daily UV radiation, as well as the UV index in order to identify the possible dose of absorbed radiation and consequently identify the relevant protection actions for the local population.

Published: June 2023

Adsorption is vital for the elimination of Cr6+ and Pb2+ ions in the contaminated solution medium. A ternary blend made up of chitosan, nylon 6 and polyurethane foam (CS/Ny 6/PUF) blend in the ratio of 2:1:1 has been investigated. These blends are used as an adsorbent due to the insoluble nature in acidic and basic medium. The adsorption efficacy was analyzed by modifying pH, contact time, and adsorbent dosage. The maximum uptake of metal ions has been exhibited in the pH range 5. An equilibrium adsorption statistic indicated that adsorption isotherm follows the Freundlich model. The adsorption kinetic parameters specified that the adsorption of chromium has shown pseudo-second-order and lead pseudo-first-order reaction.
A Novel Hypoxia-related lncRNA Risk Score Model for Prognosis Evaluation
of Clear Cell Renal Cell Carcinoma
Authors: Liu Fu , Li Xinyuan , Zhou Xiang , Tong Hang , Hu Zili , Bai Xuesong , Gou Xin
Published: June 2023

Background:

Renal cell carcinoma is the most common aggressive tumor of the genitourinary system. The main pathological subtype is clear cell renal cell carcinoma (ccRCC), and its treatment options are very limited. Therefore, identifying specific biomarkers of ccRCC is of great significance for diagnosis and prognosis.

Methods:

First, we obtained transcriptome data and clinical data of 611 patients with renal clear cell carcinoma to analyze the relationship between hypoxia-related lncRNAs and overall survival (OS). We screened hypoxia-related lncRNAs through Pearson correlation and Cox regression analysis. Univariate and multivariate regression analysis were applied to assess survival-related risk factors. According to the median risk score, patients were divided into two groups. Next, a nomogram map was built, and GSEA was used for gene function annotation. RT-qPCR, Western Blot, and Flow Cytometry were used to determine the role of SNHG19 in RCC cells.

Results:

By analyzing the co-expression of hypoxia genes and lncRNAs, 310 hypoxia-related genes were obtained. Four sHRlncRs (AC011445.2, PTOV1-AS2, AP004609.3, and SNHG19) with the highest prognostic values were included in the group to construct the HRRS model. The high-risk group had a shorter OS than the low-risk group. HRRS was considered to be an independent prognostic factor and associated with OS. The two groups showed different pathways in GSEA. Experiments showed that SNHG19 plays essential roles in the autophagy and apoptosis of RCC cells.

Conclusion:

We constructed and validated a hypoxia-related lncRNA model for ccRCC patients. This study also provides new biomarkers for the poor prognosis of ccRCC patients.
Gelatin-based Targeted Delivery Systems for Tissue Engineering
Authors: Zhai Xinyue , Wu Yuqian , Tan Huaping
Published: June 2023

Gelatin is an attractive material for drug delivery and tissue engineering applications due to its excellent biocompatibility and biodegradability, which has been utilized as cell, drug, and gene carriers. Gelatin is less immunogenic compared to collagen and its precursor and retains informational signals, such as RGD (Arg-Gly-Asp) sequence, thus promoting cell adhesion and proliferation. To tune the mechanical strength and bioactivity, gelatin can be easily modified via chemical reactions and physical methods to obtain various derivatives. Furthermore, gelatin-based biomaterials can be achieved through chemical immobilization of specific molecules and physical combination with other biopolymers. This review focuses on the recent advances of gelatin and its derivatives as biomaterials in the field of drug delivery, including cell scaffolds for tissue engineering applications.
Maternal High Fat Diet and its Expressions in the Heart and Liver in
the Mice Embryogenesis
Authors: Nirala Sanjeev , Tan Xue-Rui , Shafiq Muhammad , Basnet Rajesh , Singh Apekshya
Published: June 2023

Background:

The developmental biology for the nonalcoholic fatty liver
disease and coronary heart disease are known but elaborative ideas of triglycerides
phenomenon in the embryo-genesis of the liver and the heart are still not clear.

Objective:

The aim of the study was to relate different triglycerides like LXRα, LPL, LDL
R, PPARG-, SREBP-1C expression in the high fat fed mice with the normal fed diet
mice in the process of developmental and embryo-genesis biology.

Methods:

Tissue preparation was done by ripalysis. Different protein content was
obtained via western blot for the 6 samples namely a-17.5 days mice embryo heart; b-
0th day or the birthday mice infant heart; c-1 week mice infant heart; d-2 weeks mice
infant heart; e-3 weeks mice infant heart; f-Adult mice heart. Protein lysates from the
heart tissues of the mice was obtained via homegenization and centrifugation.
Hematoxylin and Eosin (H and E) was done to see the fat droplets in the liver tissues at
the different developmental stages.

Result:

LXRα,SREBP-1C expression in 17.5 days mice embryo heart and 0th day or
the birthday mice infant heart is highly expressed in the high fat diet. LDL-R in the high
fat diet mice is increased in 2 weeks mice infant heart but in17.5 days mice embryo
heart and in 0th day or the birthday mice infant heart it is low expression but from 1week
mice infant heart to the adult mice heart the expression is in decreasing trend. Similarly
LPL is highly expressed in17.5 days mice embryo heart and 1 week mice infant heart
and thus low expression in decreasing order until adult mice heart.Thus, these results
collectively shows that maternal HF diet increases expression of proteins such as LPL,
LDLr in the embryo phase and thus getting normal expressions in the adult phase that
facilitate Triglycerides (TAG) hydrolysis across the liver and the heart. Also,maternal
high fat diet increases the SREBP1c expression, leading to stimulation of LPL
Expression.

Conclusion:

In summary, using a pregnant mice model, we found that maternal high fat
diet increases the fetal fat accumulation. Elevated placental LPL activity and expression
of genes that facilitate placental lipid transport suggest that enhanced placental lipid
transport may play a key role in maternal nutrition and obesity-induced fetal fat
accumulation.
Analysis of Harmonic Compensation for Grid-side Current of Series
Sixfold-circuit “Phase-hopping” AC-AC Frequency Converter
Authors: Yang Jixin , Xu Zhengwang , Zhu Jin , Zhang Jiarui , Shen Shikang
Published: June 2023

Background:

A series sixfold-circuit “phase-hopping” AC-AC frequency converter
(SSCPH-AAFC) is an extension of traditional AC-AC frequency converters. Compared to traditional
frequency converters, it has the advantages of energy-saving, low cost, and simple control.
Additionally, it can increase the upper limit of the frequency conversion to the power frequency.
Through multiplexing processing, it reduces the harmonic content of the output waveform,
making it suitable for applications, such as large-capacity fan or pump speed control.

Objective:

Although SSCPH-AAFC reduces harmonic content, the harmonic content of the single-
phase and three-phase grid-side currents still reach 14.65% and 10.20%, respectively. To
meet national standards for practical application, a compensation circuit needs to be designed to
further reduce grid-side current harmonics.

Methods:

To address harmonic problems, a targeted single-phase current open-loop compensation
method was designed based on the analysis of the current waveform defect. The method
compensated for harmonics by selecting appropriate trigger angles and reducing the harmonic
distortion rate of the power grid to meet the necessary application standards.

Results:

The method was simulated and analyzed using MATLAB, and the results showed that
after single-phase open-loop compensation, the total harmonic distortion (THD) of the grid-side
current for a single-phase SSCPH-AAFC was 2.64%, and for a three-phase SSCPH-AAFC, it
was 1.80%.

Conclusion:

This method has a good effect and can meet the standard requirements.

Published: June 2023

Background:

Magnetite is the most recognized iron oxide candidate used for various biological
applications.

Objective:

This work is a complete study that addresses the synthesis of magnetic nanoparticles and
investigates the feasibility of using green tea and ascorbic acid as capping agents.

Methods:

Synthesis of magnetite by two wet chemical methods namely: coprecipitation and solvothermal
methods. The samples were characterized using X-ray diffraction (XRD), transmission
electron microscope (TEM), and vibrating sample magnetometer (VSM).

Results:

The results reveal the impact of coating on the size and morphology of the particles. The
study also proves that autoclaving the samples prepared by coprecipitation results in smaller particle
size and narrower size distribution due to digestive ripening. In addition, a novel and facile methodology
for coating magnetite with polyethylene glycol is presented. The potential of the particles to be
used for magnetic fluid hyperthermia is assessed by measuring the specific absorption rate (SAR) of
the samples.

Conclusión:

The results show that all the prepared magnetite samples showed a promising capacity to
be used as magnetic fluid hyperthermia agents.

Movimentos do Streaming e Identidade Cultural na Nova Ordem dos Remakes Transnacionais
Authors: Parrot Alexis
Published: June 2023

O advento das plataformas de streaming instaurou novas demandas e paradigmas, gerando uma necessária reconfiguração dos processos de criação e produção dos conteúdos e formatos televisivos. Categoria recorrente da televisão tradicional, o remake transnacional passa a se manifestar com outros contornos, submetido a uma nova ordem de práticas e significados. Da exibição local à global, o que se ganha e o que se perde na tradução? A partir da proposta de uma sistematização das estratégias empregadas pela indústria do streaming na realização e exibição de remakes transnacionais, o presente artigo organiza um percurso apoiado na análise de algumas franquias transnacionais de ficção seriada da era do broadcasting (The Office [O Escritório] e Bron/Broen [A Ponte]) e do streaming (Dix Pour Cent [Dez por Cento] e La Casa de Papel [A Casa de Papel]), reconhecendo o papel de liderança da Netflix no setor. Estruturada cronologicamente em "movimentos", tal sistematização se inspira na analogia criada por Erwin Panofsky (1978) entre o filme e a catedral medieval e caminha em paralelo à timeline histórica dos modelos de negócios da Netflix, conforme convencionada por Laura Osur (2016). Espera-se que as conclusões obtidas ofereçam subsídios pertinentes para o debate sobre remakes transnacionais na televisão, destacando sua contribuição para os processos de afirmação cultural e construção identitária das realidades que representam.

Authors: Larkins Nicholas G. , Lim Wai , Goh Carrie , Francis Anna , McCarthy Hugh , Kim Siah , Wong Germaine , Craig Jonathan C.
Published: June 2023

Background

No randomized trials exist to guide the timing of the initiation of KRT in children. We sought to define trends and predictors of the eGFR at initiation of KRT, center-related clinical practice variation, and any association with patient survival.

Methods

Children and young adults (1–25 years) commencing KRT (dialysis or kidney transplantation) between 1995 and 2018 were included using data from the Australia and New Zealand Dialysis and Transplant Registry. The associations between eGFR on commencing KRT and covariates were estimated using quantile regression. Cox regression was used to estimate the association between eGFR and patient survival. Logistic regression, categorizing eGFR about a value of 10 ml/min per 1.73 m2, was used in conjunction with a random effect by center to quantify clinical practice variation.

Results

Overall, 2274 participants were included. The median eGFR at KRT initiation increased from 7 to 9 ml/min per 1.73 m2 over the study period and the 90th centile from 11 to 17 ml/min per 1.73 m2. The effect of era on median eGFR was modified by modality, with a greater increase among those receiving a preemptive kidney transplant (1.0 ml/min per 1.73 m2 per 5 years; 95% confidence interval [CI], 0.6 to 1.5) or peritoneal dialysis (0.7 ml/min per 1.73 m2 per 5 years; 95% CI, 0.4 to 0.9) compared with hemodialysis (0.1 ml/min per 1.73 m2 per 5 years; 95% CI, −0.1 to 0.3). There were 252 deaths (median follow-up 8.5 years, interquartile range 3.7–14.2) and no association between eGFR and survival (hazard ratio, 1.01 per ml/min per 1.73 m2; 95% CI, 0.98 to 1.04). Center variation explained 6% of the total variance in the odds of initiating KRT earlier. This rose to over 10% when comparing pediatric centers alone.

Conclusions

Children and young adults progressively commenced KRT earlier. This change was more pronounced for children starting peritoneal dialysis or receiving a preemptive kidney transplant. Earlier initiation of KRT was not associated with any difference in patient survival. A substantial proportion of clinical practice variation was due to center variation alone.

Rice Value Chain Analysis: Rice Seed Production as a Profitable Agribusiness in Nueva Ecija
Authors: A. Hilado Angie Rose , S. Hugo Jayries , D. Kodama Hikari , P. Lebite Jerald , G. Fronda Jennifer
Published: June 2023

This study explored the rice value chain (RVC) in Nueva Ecija, value additions, found restrictions, and offered to upgrade solutions to improve the competitiveness of the rice industry and specific segments in the RVC using the value chain analysis (VCA) methodology. Farmers, paddy dealers, millers, wholesalers, wholesaler-retailers, and retailers in Nueva Ecija provided primary data. Workshops with stakeholders were also held to validate preliminary findings and identify upgrading strategies. The RVC begins with the provision of inputs for paddy production and concludes with the consumption of milled rice. The RVC is dominated by a traditional multi-layered supply chain with interconnected chain actors consisting of competing farmers, paddy traders, millers, and rice traders in each segment and, frequently, with the involvement of brokers in both paddy aggregation and rice distribution, thereby increasing marketing cost. The major constraints identified in the RVC included high production and marketing costs of paddy and rice due to low yield, high labor and material inputs, and a lack of critical infrastructure and market facilities (e.g., modern mills, dryers, cheap transport, and energy), resulting in high domestic paddy and rice prices and low competitiveness of the entire rice VC. To improve competitiveness, the rice industry should focus on developing and promoting yield-increasing, postharvest loss-reducing, and cost-cutting technologies, as well as those that improve overall RVC efficiency, such as investments in enabling infrastructure and facilities for transport, handling, storage, drying, and milling.

Bioactive Peptides in Meat and Meat Products
Authors: Toldrá Fidel , Reig Milagro , Gallego Marta , Mora Leticia
Published: June 2023

A number of bioactive peptides with health benefits have been reported to be generated in meat through the proteolysis phenomena taking place during postmortem aging or further processing. Bioactive peptides consist of short sequences, less than 20 amino acid residues, that are inactive while in the parent protein. These sequences may be activated when they are released from the parent protein by peptidases. Such peptides are released through the hydrolysis of major muscle proteins by muscle endopeptidases, like calpains and cathepsins, and resulting protein fragments and polypeptides are further hydrolyzed by muscle exopeptidases, mainly, tri- and di-peptidylpeptidases, aminopeptidases, and carboxypeptidases. As a result, a variety of peptides with different sequences and lengths and large amounts of free amino acids are generated. The highest amounts of bioactive peptides, and their major health benefits, have been reported in dry-cured ham as a result of the intense proteolysis experienced during the long processing time under mild conditions that favor the action of muscle peptidases. The generated peptides must be bioaccesible and bioavailable to exert their physiological benefit.This means that they must be resistant to gastrointestinal digestion and be absorbed through the intestinal barrier. Some bioactive peptides may be generated through hydrolysis during gastrointestinal digestion. This review is focused on the generation of bioactive peptides in meat and processed meats, on the most relevant bioactivities exerted by such peptides(such as inhibition of angiotensin I–converting enzyme and dipeptidyl peptidase IV as well as antioxidant and anti-inflammatory activity), and on their reported benefits to consumers’health.

Literature Review on the Fabrication of Hybrid Engine Vehicle
Authors: Ingle Dr. A. H.
Published: June 2023

Abstract: A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine + electric motor, e.g. in diesel-electric trains using diesel engines and electricity from overhead lines, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid, in hydraulic hybrids. A water-fuelled car is an automobile that hypothetically derives its energy directly from water. Water-fuelled cars have been the subject of numerous international patents, newspaper and popular science magazine articles, local television news coverage, and websites. The claims for these devices have been found to be pseudoscience and some were found to be tied to investment frauds. These vehicles may be claimed to produce fuel from water on board with no other energy input, or may be a hybrid claiming to derive some of its energy from water in addition to a conventional source (such as gasoline). Water is fully oxidized hydrogen. Hydrogen itself is a high-energy, flammable substance, but its useful energy is released when water is formed. Water will not burn. The process of electrolysis can split water into hydrogen and oxygen, but it takes as much energy to take apart a water molecule as was released when the hydrogen was oxidized to form water. In fact, some energy would be lost in converting water to hydrogen and then burning the hydrogen because some waste heat would always be produced in the conversions. Releasing chemical energy from water, in excess or in equal proportion to the energy required to facilitate such production, would therefore violate the first or second law of thermodynamics.

Abstract: Steganography and Digital Watermarking are two methods of information concealment in which the context can be interpreted as keeping the information hidden or making it subtle. Steganography is a means of disguising an information so that only the person(s) who placed it are aware of its existence. Onthe other hand digitalwatermarking is the technique of inserting a symbol of some form into a media file to differentiate it from others. Security authenticationis intended to be permanent, and it is applied by a process that involves changes to the media file. Other parties may be able to see or hide digital watermarking in plain sight. In this paper we are going to review the steganography techniques. This paper will do a whole comparativestudy of different steganography techniques also.
Experimental Study on Behaviour of Paver Block using Granite Powder
Authors: Shrivastava Aman
Published: June 2023

Abstract: One of the most common materials for pavement applications is pre-cast concrete paver blocks. However, they need a lot of cement, which is expensive and harmful to the environment. Cement is the main ingredient in any concrete mix, but its production and transportation costs are high. Moreover, it causes air pollution when produced on a large scale. Therefore, there is a need to find an alternative or substitute for cement industry. This study explores the possibility of using 30% granite powder by weight instead of cement in paver block production. Granite powder is a waste material from the granite industry in India, which produces more than 3500 cubic meters of it every day. The granite polishing process also generates tons of granite dust, which is not used and disposed on the land. This creates environmental and health problems due to its high alkalinity and air pollution. It also occupies a lot of land space for disposal.

Authors: Shesham Shilpa , Muskar Monish , Vardhineni Tanish , Gannavarapu Bhavana Preethika
Published: June 2023

Abstract: This Poor sitting posture is a common cause of low back pain, as it places excessive pressure on muscles and discs. To address this issue, smart office chairs have been developed using IoT, wireless communication, sensing, and intelligent control technologies. This paper proposes and implements a system for detecting incorrect sitting positions using a smart chair equipped with two tactile pressure sensor mats, vibration actuators, NodeMCU , a data acquisition module, and a cloud server. The system notifies users of incorrect sitting positions through visual and vibration feedback, which is received through a mobile application. Simple rules were defined to process sensor data to recognize wrong sitting postures, and the data collected from smart chairs were stored in a MongoDB database using a private cloud solution from QNAP. The Node-RED application was proposed for the entire logic implementation.

Published: June 2023

Objectives The purpose of this study were to explore the semantic norm of Hangul words based on type of semantic relationship. We investigated various words that exhibited diverse types of semantic relationships with a single word. Methods We conducted a free association task and controlled association task on 180 Hangul words with 150 adults over the age of 20 who were native Korean speakers. In the free association task, participants were asked to freely report words that came to mind when presented with a given word, while in the controlled association task, they were asked to report words related to the given word semantically, categorically, or functionally. Results The words reported in the free association task were found to overlap with those reported in the controlled association task for the same given word in approximately 74% of cases. Specifically, categorical related words were the most common, accounting for 52%. Subsequently, functional-related words, semantic-related words, and pure associative words constituted the majority of the sample, in descending order. In the free association task, it was found that higher word frequency was associated with a greater number of words generated. However, in the controlled association task, such a correlation was not observed. Conclusions While some cases existed where words related by association differed in their semantic, categorical, or functional relationships, the majority of these words were common. Thus, when designing learning materials, it is crucial to take these factors into account, as words with semantic relationships are likely to be retrieved together.

Objectives This study examines the difficulties and requirements of early childhood teachers' field trips due to COVID-19, and through this, aims to provide basic data on field trip methods that can effectively cope with crisis situations such as pandemics. Methods 102 homeroom teachers aged 3 to 5 working at an early childhood education institution located in Yongin-si, Gyeonggi-do participated, and the survey was conducted through an open-ended questionnaire. Specific examples and requirements for difficulties in field trips due to the COVID-19 pandemic were described. Results First, the difficulties of early childhood teachers' field trips due to the COVID-19 pandemic are ‘difficulties in supporting teaching and learning linked to play topics’, ‘difficulties due to parents' various requests and non-cooperation’, and ‘difficulty in selecting a site for field trips’. appeared. Second, the requirements of early childhood teachers for effective field trips in the context of the COVID-19 pandemic are ‘institutional support for safe field trips’, ‘parental awareness improvement support for field trips linked to children's play’, It turned out to be ‘educational support for high-quality field trips’. Conclusions In order to effectively implement field trips in a pandemic situation such as COVID-19, it was discussed that a systematic system is needed so that the government, local governments, early childhood education institutions, and families can communicate and share together.

This study examines the learning experience of Chinese international undergraduate students taking a large core first-year anthropological science course (ANT101) by distance learning during the Winter of 2021 at the University of Toronto Mississauga (UTM). By analyzing qualitative and quantitative data collected from self-report pre- and post- course surveys (n=587), we review the general learning experience of Chinese international students (n=30) in comparison to other international students (n=34) and domestic students (n=523). Our study shows support, but at the same time undermines some prevailing notions about Chinese international student experiences of studying in Western universities. Our data suggests that while many Chinese international students may feel a lack of English language proficiency is a barrier to their learning, it does not significantly impact their performance when compared with domestic students. The preliminary results suggest that educational research and policy makers should move beyond a focus on language proficiency and examine the role of other factors when developing strategies to facilitate supportive learning environments for English Language learners (ELL) and international students in a university setting.

Integrating educational assessment tools such as the Motivated Strategies for Learning Questionnaire (MSLQ) into university classrooms can help students and faculty gain insight into areas of strength and challenge for students. The present study adapted and integrated the MSLQ into a set of first-year communication courses for Faculty of Arts students at the University of Waterloo. This adaptation allowed us to better situate the scale within the writing and communication course context. Through exploratory and confirmatory analysis, a shortened questionnaire (MSLQ-AF) with 6 subscales (motivation, academic self-confidence, performance anxiety, critical thinking, planning for optimal learning, and peer learning) was created. MSLQ-AF proved to have stable factor structure, adequate and stable internal consistency, and construct validity (correlation with grades), when assessed across four samples spanning four university terms. We discuss the role of this new scale in helping students transition into university.
Failing to Learn: Design Thinking and the Development of a Failure-Positive Mindset in the University Classroom
Authors: Dorland AnneMarie
Published: June 2023

Meaningful and impactful learning experiences are rife with failure. And yet, students struggle with framing, tolerating and attributing failure in a positive manner within the post secondary learning context. This paper explores whether using design thinking as a pedagogical approach might help students learn to tolerate, reframe and attribute failure in a more productive way. Findings from this comparative study of 600 undergraduate business students enrolled in a common first year marketing class reveal the ways in which design thinking-based learning approaches might be used to re-orient student’s conceptions of failure as a part of their creative problem-solving skill development process. Students were surveyed to learn more about how they perceived the concept of failure within their learning, to whom they attributed failures within their learning, and how well they tolerated failure as a part of their learning experience. Results from the nearly 400 responses to the online survey suggest that integrating design thinking focused approaches to learning into the post secondary classroom has a positive impact on the development of a student’s self-reported failure tolerance and may change the way that failure is attributed and framed in students’ descriptions of their individual learning. I find that design thinking-based learning might be used as an effective pedagogical approach in classes where the development of a failure-positive mindset is considered an essential competency or learning objective, and I offer practical recommendations for educators seeking to develop a failure-positive mindset within their learning communities.
On Quantum Steering and Wigner Negativity
Authors: Walschaers Mattia
Published: June 2023

Quantum correlations and Wigner negativity are two important signatures of nonclassicality in continuous-variable quantum systems. In this work, we investigate how both are intertwined in the context of the conditional generation of Wigner negativity. It was previously shown that when Alice and Bob share a Gaussian state, Bob can perform some measurement on his system to create Wigner negativity on Alice's side if and only if there is Gaussian steering from Alice to Bob. In this work, we attempt to generalise these findings to a much broader class of scenarios on which Alice and Bob share a non-Gaussian state. We show that if Alice can initially steer Bob's system with Wigner-positive measurements, Bob can remotely create Wigner negativity in Alice's subsystem. Even though this shows that quantum steering is sufficient, we also show that quantum correlations are in general not necessary for the conditional generation of Wigner negativity.

Some countries have an old scholarly tradition of studying this plot. Such well-known philologists as Alexander Veselovsky in Russia and Bogdan Petriceicu Hasdeu in Romania wrote about it as early as the 19th century. In the 20th century, this text was studied a lot in Italy, Germany, Romania, Russia, etc. The article proposes a preliminary classification of the main genre versions of the “Dream of the Virgin” in Russian manuscript and folklore traditions.
