Tianguis Regional Universitario proyecto potenciador de los medios de vida sostenibles en artesanos y productores de la Sierra Gorda Queretana

Los medios de vida sostenibles constituyen un enfoque para evaluar tanto las condiciones de vida de un grupo de personas, como el impacto que una actividad o programa genera en ese grupo social. Desde 2016 el Tianguis Regional Universitario otorga a productores y artesanos de la Sierra Gorda Queretana (SGQ) la posibilidad de dar a conocer y comercializar sus productos directamente a los consumidores locales y turistas. El proyecto fue iniciativa de la Universidad Autónoma de Querétaro Campus Jalpan, en coordinación con el Museo Histórico de la Sierra Gorda y las áreas de turismo de los Municipios de Arroyo Seco, Landa de Matamoros y Jalpan de Serra y tiene como objetivo promover el comercio justo. A seis años de su implementación, y a partir de un estudio mixto de naturaleza exploratoria, se valoró el estado de los medios de vida sostenibles en los participantes. Se aplicó una encuesta a 21 artesanos y productores, así como un grupo focal. Del análisis de la información se desprendieron las oportunidades de mejoras a esta actividad de vinculación.
Evaluation and Comparison of Sensitivity and Specificity of Ultrasonography in Placenta Accreta Diagnosis in the Second and Third Trimesters

Background: Ultrasound is the selected technique for the detection of placenta accreta spectrum (PAS). This method can detect PAS in 80%-50% of cases. This study aimed to assess and compare the sensitivity and specificity of ultrasonography in the diagnosis of PAS after the first trimester. Materials and Methods: In this prospective study that was performed in 2020-2021 on 79 patients at high risk of PAS, all cases underwent ultrasonography in both 18-22 weeks of gestational age (GA) and 32-34 weeks of GA for evaluation of accreta. As per the risk factors, the delivery plan for all mothers was cesarean section. During the cesarean section, the placenta was examined for accreta, and if it was attached to the uterus, a diagnosis of placenta accreta was ascertained and a total abdominal hysterectomy was performed if the patient's bleeding was not controlled during the operation. The final diagnosis of PAS was made based on the pathology report. Results: Ultrasound evaluation for PAS in 18-22 weeks of GA had 79.17% specificity, 51.61% sensitivity, 61.54% positive predictive value, and 71.70% negative predictive value. Ultrasound imaging for PAS in 32-34 weeks of GA had 60.8% specificity, 90% sensitivity, 62.52% positive predictive value, and 90.33% negative predictive value. Conclusion: It should be concluded that PAS is a critical condition and if the patient is diagnosed in the second or third trimester, special strategies should be applied.
Minimally Invasive Direct In-Situ Magnetic Loss Measurement in Power Electronic Circuits

Designing a good magnetic component is essential for achieving high efficiency in power converters. However, validating such a design is difficult, especially when the power converter operates in the desired condition. Accurate direct in-situ magnetic loss measurement has been known as unattainable due to an unknown timing skew between measurement channels. The unavoidable timing skew, arising from various reasons, can introduce highly excessive measurement errors, rendering the direct in-situ loss measurement unfit to be used in reality. This article proposes a novel method to eliminate the errors associated with the timing skew and make the accurate, direct, and in-situ magnetic loss measurement practical and minimally invasive. The new method, termed as improved dual-curve derivative method, is introduced and analyzed in detail based on mathematical models. Compared to the existing methods, the novel method achieves more accurate measurements while reducing invasiveness to the power converter. The operational principles and performance of the improved dual-curve derivative method are verified in simulation and validated in experiments in a dc–dc step-down buck converter, subject to various realistic circuit parameters.
α-Tubulin Mutation Thr-239-Ile in Annual Bluegrass (Poa annua) Induces Variable Responses to Prodiamine and Dithiopyr

Abstract Mitotic-inhibiting herbicides, like prodiamine and dithiopyr, are used to control annual bluegrass (Poa annua L.) preemergence in managed turfgrass; however, resistance to mitotic-inhibiting herbicides has evolved due to repeated applications of herbicide from a single mechanism of action. Three suspected resistant populations (R1, R2, and R3) were collected in Alabama and Florida and screened for resistance to prodiamine. Part of the α-tubulin gene was sequenced for known target-site mutations. Target-site mutations were reported in all three R populations, with each containing an amino acid substitution at position 239 from threonine to isoleucine (Thr-239-Ile). Previous research has indicated that the Thr-239-Ile mutation confers resistance to dinitroaniline herbicides in other species. Dose–response screens using prodiamine and dithiopyr were conducted and I50 values were calculated for R1, R2, and R3 using regression models based on seedling emergence. For prodiamine, I50 values for R1, R2, and R3 were 35.3, 502.7, and 91.5 g ai ha–1, respectively, resulting in 2.9-, 41.9-, and 7.6-fold resistance, respectively, when compared with a susceptible (S) population. For dithiopyr, I50 values for R1, R2, and R3 were 154.0, 114.2, and 190.1 g ai ha–1, respectively, resulting in 3.6-, 2.7-, and 4.5-fold resistance, respectively, when compared with an S population. When comparing I90 values with the highest labeled use rates, R2 had a 2.9-fold level of resistance to prodiamine, and R1, R2, and R3 had a 2.4-, 2.0-, and 3.2-fold levels of resistance to dithiopyr, respectively. This is the first report of a variable response in P. annua to prodiamine despite each R population possessing the same mutation.
Problems in IoT Networks: Usage, Infrastructure, And Engineering of Industrial IoT Applications

The term "Things (Iot," sometimes known as "World wide web of Almost everything," refers to a network of physical items that have circuitry that allows interaction over wireless networks or wired networks (such as the World wide web) for a variety of functions, such as gps tracking or control. The availability of a web app via which a user may connect the home's technology helps to improve productivity and save costs. The use of linked IoT settings will help not just businesses, but also towns, hospitals, industries, and state agencies. These settings are defined by the transfer of data across tools, gadgets, and people as well as these tools and gadgets. This study examines the advantages of Iot applications used in businesses from several angles. In order to make references to actual events and circumstances, we use a specific example. This article's other goal is to provide a model of architectural for the platforms and investigate how they work by examining the technology used to create them or the security risks that may be solved.
Analysis of Cross-Coupling Effect for Multi-Objective Wireless Power Transfer

In this paper, a quantitative analysis of the cross-coupling effect for multi-objective wireless power transfer (WPT) is presented and a relevant method to eliminate the influence is implemented. Based on the exemplified two-pickup and three-pickup WPT systems, the wirelessly transmitted power and efficiency are significantly affected by the cross-coupling effects among pickup coils. Meanwhile, the zero-phase angle (ZPA) operation of the primary side is deteriorated due to the existence of the cross-coupling effect. Accordingly, a cross-coupling cancellation method is proposed to regulate the primary exciting current back to its original value and recover the primary side back to the ZPA operation. Both the simulated and experimental results are provided to verify the feasibility of the proposed cancelation method.
Lattices and Manifolds of Classes of Flat Riemannian Tori

The topological and differentiable structures of some natural quotient spaces constructed from flat Riemannian tori are studied by means of a cut-and-paste procedure (concretely, H\(Gl(2,R)/Sl(2, Z)), where H = O(2,R), CO(2,R), O(2,R), CO(2,R)). In the orientation preserving cases, the quotients can be regarded as manifolds with singular points corresponding to lattices in the square and hexagonal crystal systems. In the non-orientation preserving ones, the natural structure is a smooth manifold with piecewise smooth boundary, where the interior points correspond to oblique lattices, the regular points of the boundary to rectangular and centered rectangular lattices and the edge of the boundary to square and hexagonal ones.
Quantized RIS-Aided Multi-User Secure Beamforming Against Multiple Eavesdroppers

This paper focuses on a network scenario where a multi-antenna access point serves multiple single-antenna users in the presence of multiple eavesdroppers, with the aid of a reconfigurable intelligent surface (RIS). The RIS employs low-resolution programmable reflecting elements (PREs) for cost-effective implementation. In order to establish secure links for all users, we consider the joint design of the transmit beamformers and PREs to maximize either the geometric mean of secrecy rates or the worst user’s secrecy rate. Novel computational algorithms of low computational complexity are developed for the solution of these mixed discrete continuous optimization problems. Simulations show the merit of the proposed designs in in achieving fair secrecy rate distributions and ensuring secure links for all users.
Hotspot advance speed - hotspot size/core-hotspot distance relation

We examined the evolution of extragalactic radio sources using the observed corehotspot distance and hotspot size. Analysis indicates a fairly strong positive correlation in the ratio of core-hotspot distance to hotspot size between that of the approaching arm and the receding arm with a correlation coefficient of r ~ 0.7. Simple kinematic consideration enabled us to obtain an expression to constrain the advance speed of hotspots. In general, the average projected hotspot advance speed estimated for our sample ranges from 0.13 ≤ 〈 β 〉 ≤ 0.40.

A current transient method for trap analysis in BiFeO3 thin films

We present a method to study the trap characteristics in BiFeO3 thin films, which display a resistance switching effect caused by trapping/detrapping of charge carriers. The method consists of measuring the current transients for the detrapping of charge carriers from trap sites and subsequent analysis of the time constant from the current transient curve. Using this method, the energy level of the traps was identified to be 0.71 ± 0.06 eV. The parameters of the trapping pulses (voltage and time duration) were found to affect the time constant, indicating a close relationship between the escape frequency of the charge carriers and the structure ordering caused by polarization and the filling of the traps.We present a method to study the trap characteristics in BiFeO3 thin films, which display a resistance switching effect caused by trapping/detrapping of charge carriers.

Metabolite Profiling in a Diet-Induced Obesity Mouse Model and Individuals with Diabetes: A Combined Mass Spectrometry and Proton Nuclear Magnetic Resonance Spectroscopy Study

Mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy techniques have been used extensively for metabolite profiling. Although combining these two analytical modalities has the potential of enhancing metabolite coverage, such studies are sparse. In this study we test the hypothesis that combining the metabolic information obtained using liquid chromatography (LC) MS and 1H NMR spectroscopy improves the discrimination of metabolic disease development. We induced metabolic syndrome in male mice using a high-fat diet (HFD) exposure and performed LC-MS and NMR spectroscopy on plasma samples collected after 1 and 8 weeks of dietary intervention. In an orthogonal projection to latent structures (OPLS) analysis, we observed that combining MS and NMR was stronger than each analytical method alone at determining effects of both HFD feeding and time-on-diet. We then tested our metabolomics approach on plasma from 56 individuals from the Malmö Diet and Cancer Study (MDCS) cohort. All metabolic pathways impacted by HFD feeding in mice were confirmed to be affected by diabetes in the MDCS cohort, and most prominent HFD-induced metabolite concentration changes in mice were also associated with metabolic syndrome parameters in humans. The main drivers of metabolic disease discrimination emanating from the present study included plasma levels of xanthine, hippurate, 2-hydroxyisovalerate, S-adenosylhomocysteine and dimethylguanidino valeric acid. In conclusion, our combined NMR-MS approach provided a snapshot of metabolic imbalances in humans and a mouse model, which was improved over employment of each analytical method alone.
On the maximal cycle and transient lengths of circular cellular automata

We prove some conjectures about the maximal cycle and transient lengths of circular cellular automata. These conjectures were left open in the PhD. thesis of Dr. B. Rinaldi. We also prove theorems on the number of circular cellular automata rules that implement these maximal lengths, and characterize completely the set of the possible cycle and transient lengths.

A Mathematical Analysis of Scale Similarity

Scale similarity is found in many natural phenomena in the universe, from fluid dynamics to astrophysics. In large eddy simulations of turbulent flows, some sub-grid scale (SGS) models are based on scale similarity. The earliest scale similarity SGS model was developed by Bardina et al., which produced SGS stresses with good correlation to the true stresses. In the present study, we perform a mathematical analysis of scale similarity. The analysis has revealed that the ratio of the resolved stress to the SGS stress is γ2, where γ is the ratio of the second filter width to the first filter width, under the assumption of small filter width. The implications of this analysis are discussed in the context of large eddy simulation. AMS subject classifications: 35L65, 76F02
Novel Metallo-β-Lactamase blaCVI-1 Isolated from a Chromobaterium violaceum Clinical Strain Resistant to Colistin

Objective: We aimed to describe a colistin (COL)-resistant (R) Chromobacterium violaceum (Cvi) isolate from a septic patient in Argentina expressing a previously unknown gene, blaCVI-1. Methods: In 2019, a 12 year old child was injured with a thorn in a lagoon. The child was hospitalized due to sepsis and multiple abscesses. Cvi was isolated from skin and soft tissue and tracheal aspirate. The patient was successfully treated with imipenem (IMI) plus amikacin. Antimicrobial susceptibility was assessed by disk diffusion, broth microdilution, and the E-test. Carbapenemase activity was assayed by double-disk synergy and microbiological tests. Resistance, virulence, and additional gene searches were performed by in silico analysis of sequences obtained by whole-genome sequencing (WGS). A maximum likelihood phylogenetic tree was built with public Cvi genomes. Results: R was seen for IMI and COL. Expression of a metallo-β-lactamase was confirmed. Genome analysis revealed blaCVI-1, a subclass B2 metallo-β-lactamase with 62.66% ID with CphA from A. hydrophila (WP081086394). R to COL could be attributed to the arnC and arnT genes. Virulence factors required for invasion and toxicity were also found. No plasmids were detected. The phylogeny tree showed two main clades with geographical distinction, and the isolate studied here stands alone in a branch closely related to two clinical isolates from the USA. Conclusions: This is the second report of infection by Cvi in Argentina. This pathogen carried a new gene, blaCVI-1, a metallo-β-lactamase that can be detected by routine methods. Prompt suspicion of C. violaceum infection is crucial to treating this rare pathogen rapidly and properly.
Multi-temporal anomaly detection technique

In this paper, we present a variation on the LRX (Local RX) algorithm for detecting anomalies in multi-temporal images. Our algorithm assigns a relative weight to the Mahalanobis distance according to the number of times it appears in an image. Standard transitions between pixels are therefore not viewed as anomalous; unusual transitions are assigned proportionally higher weights. Experimental results using our proposed algorithm vs previous algorithms on multitemporal datasets show a significant improvement.
The Development of Rhythmic Balance Training Equipment and its Effect on Performance for Elderly

The elderly accounted for 13.1% of the entire population of Korea in 2015, with 6,624,000 individuals, and are projected to account for 40% of the total population in 2060. The drastic increase in medical expenses for the elderly (3,220,000 Won per person in 2014) is becoming a social problem (StatisticsKorea, 2015). From a social welfare point of view, the idea of disseminating various types of exercise equipment to reduce medical expenses for the elderly is spreading (Josephs, Pratt, Meadows, Thurmond, & Wagner, 2016). Exercise training programs for the elderly have evolved in different ways. Korean exercise training programs such as Pilates (Kim, Rhyu, & Hong, 2011; Kang & Jon, 2014), walking (Choi & Lee, 2013; Kim & Beak, 2016), and step box (Kim, Choi, & Kim, 2016) have been used to promote exercise among the elderly. Internationally, training programs using dance (Kattenstroth, Kolankowska, Kalisch, & Dinse, 2010; Rahal et al., 2015), resistance bands (Wessner, 2016; Nemček & Simon, 2016; Oh et al., 2016), square-stepping exercise (Teixeira et al., 2013_ENREF_17; Jindo et al., 2016), and resistance with dumbbells, barbells, or cable have been recently used among the elderly (Peltonen, Arokoski, Kallinen, & Pullinen, 2012). A 2013 study by Jorgensen, Laessoe, Hendriksen, Nielsen, & Aagaard reported that most training programs for the elderly are composed of simple exercises, and more entertaining programs are needed to replace monotonous exercise programs. Park, Kim, Kim, Lee & Lim in 2010 also emphasized the need for development of an exercise program for the elderly with music and choreography to maintain interest. Nintendo's Wii Fit (Jorgensen et al., 2013), which was developed in Japan, maintains the user's interest by providing numerous programs such as yoga, strength and cardiovascular exercise training, and balance games. Because Wii Fit is a program in which the user simply repeats the motion shown on the screen, it is debatable whether Wii Fit can effectively provide exercise training with only the user's weight and strength. Only a few pieces of exercise equipment designed for the elderly are used in Korea and overseas. As several previous studies show, exercise training for the elderly has mostly been conducted using tools (tilting boards, foam plates, dumbbells, and resistance training machines) rather than equipment (Gillespie et al., 2009; Patil et al., 2015). Many pieces of exercise equipment have been developed for the elderly with a focus on rehabilitation, however. In Japan, water resistance equipment has been developed in which the user wears sock-like devices and walks forward in water to increase lower limb strength and balance (Katsura KJSB Korean Journal of Sport Biomechanics 2016; 26(3): 323-331 http://dx.doi. org/10.5103/KJSB.2016. 26.3. 323 http://e-kjsb.org eISSN 2093-9752 ORIGINAL
Macrophage-Based Therapeutic Strategies in Hematologic Malignancies

Simple Summary Tumor-associated macrophages (TAMs) are the most prevalent immunosuppressive myeloid cells in the tumor microenvironment, playing significant functions in the regulation of tumor progression, invasion, and metastatic processes. The M1 and M2-polarized phenotypes of TAMs (immunostimulatory and immunosuppressive myeloid cells, respectively) have been potentially implicated in various cancers and autoimmune diseases. Understanding the precise function of TAMs could improve the assessment of the cancer response to T cell-based treatments and reverse tumor resistance to conventional therapies. Here, the involvement of TAMs in the development of various cancers, mainly hematologic tumors, and their pleiotropic activities are comprehensively discussed. Abstract Macrophages are types of immune cells, with ambivalent functions in tumor growth, which depend on the specific environment in which they reside. Tumor-associated macrophages (TAMs) are a diverse population of immunosuppressive myeloid cells that play significant roles in several malignancies. TAM infiltration in malignancies has been linked to a poor prognosis and limited response to treatments, including those using checkpoint inhibitors. Understanding the precise mechanisms through which macrophages contribute to tumor growth is an active area of research as targeting these cells may offer potential therapeutic approaches for cancer treatment. Numerous investigations have focused on anti-TAM-based methods that try to eliminate, rewire, or target the functional mediators released by these cells. Considering the importance of these strategies in the reversion of tumor resistance to conventional therapies and immune modulatory vaccination could be an appealing approach for the immunosuppressive targeting of myeloid cells in the tumor microenvironment (TME). The combination of reprogramming and TAM depletion is a special feature of this approach compared to other clinical strategies. Thus, the present review aims to comprehensively overview the pleiotropic activities of TAMs and their involvement in various stages of cancer development as a potent drug target, with a focus on hematologic tumors.
