APOLOGÍA CRÍTICA DE LA REPARACIÓN INTEGRAL A LA VÍCTIMA DEL DELITO EN MÉXICO: ¿EL DERECHO VICTIMAL COMO LEGISLACIÓN SIMBÓLICA?
Authors: García Flores Alan Jair
Published: October 2020

El presente artículo tiene como finalidad analizar desde la perspectiva de los métodos: dogmático-jurídico; sistemático jurídico; y, análisis de contenido, el diseño normativo de la obligación estatal de garantizar la reparación integral a las víctimas del delito consagradas en el numeral 1 de la Ley General de Víctimas. Asimismo, se aspira a demostrar el sentido simbólico de la ambigüedad normativa de los sujetos obligados por ministerio de ley para proteger la dignidad del sujeto pasivo del delito u ofendido, quien se encuentra en estado de indefensión ante una revictimización inherente al actuar del Estado mexicano.  En este sentido, se ofrece una aproximación al concepto de Derecho Victimal como estandarte garantista adoptado mediante la justicia restaurativa impulsada a través de la reforma constitucional en materia penal. Finalmente, se concibe un estudio de las políticas públicas tradicionales frente a las políticas públicas con perspectiva de derechos humanos para determinar si en efecto, el diseño normativo de la obligación estatal de garantizar la reparación integral a las víctimas del delito se ajusta al paradigma proteccionista impulsado mediante la reforma constitucional en materia de derechos humanos.

EL CONTROL DEMOCRÁTICO DE LAS FUERZAS ARMADAS: UNA INTRODUCCIÓN
Authors: Hernández Carrasco Hugo Ernesto , Sánchez de la Barquera y Arroyo Herminio
Published: October 2020

A diferencia de lo que ocurre en otras regiones del planeta, como América del Norte y Europa, en América Latina las políticas de defensa nacional constituyen uno de los temas no sólo menos estudiados por el mundo académico, sino que también presentan un menor debate técnico y acusan una pasmosa falta de modernización en lo que respecta a la existencia formal de una instancia civil en relación con lo militar, en las formas de articulación del sector “Defensa” con otros sectores del gobierno, en lo que se refiere a una adecuación de una comprensión político-estratégica con relación a los conflictos (internos y externos, presentes y futuros), a la eficiencia del gasto, a la capacidad de coordinación entre las armas y al desarrollo de las fuerzas armadas vinculado a la existencia de una conducción civil institucional (cfr. Escobar 1995: 4).
UN MODELO DE CONTROL JUDICIAL DIFUSO DE CONVENCIONALIDAD Y DE CONSTITUCIONALIDAD PARA LA JURISDICCIÓN CONTENCIOSO -ADMINISTRATIVA IBEROAMERICANA (NOTAS)
Authors: García Morelos Gumesindo
Published: October 2020

El proceso contencioso-administrativo constituye una garantía jurisdiccional directa de los derechos humanos frente a los poderes de la administración pública, y en cierta medida frente a los poderes legislativos cuando se inaplican porciones normativas de aquellos ordenamientos aprobados por dichos órganos políticos. Dicho medio de control guarda una profunda cercanía respecto al proceso constitucional de amparo, ya que ambos recursos judiciales tienen una semejanza en los accesos ante los tribunales por parte de los ciudadanos.El Derecho procesal administrativo se ha nutrido de importantes consideraciones doctrinales y jurisprudenciales a lo largo de los años. Fruto de lo anterior es la construcción de un nuevo régimen jurídico de la citada garantía, que permita a nuestros países hermanos adoptar ideales comunes plasmados en el Código Modelo de procesos administrativos-judicial y extrajudicial -para Iberoamérica.
EL FEDERALISMO JUDICIAL Y LOS DERECHOS HUMANOS EN VERACRUZ
Authors: Muñiz Díaz Carlos
Published: October 2020

El objetivo general de esta investigación es explicar cómo se integran la protección federal de los derechos humanos en México y la protección estatal, tomando como referencia el caso del Estado de Veracruz.Los derechos establecidos en la Constitución General de los Estados Unidos Mexicanos contienen los derechos mínimos y son susceptibles de ser ampliados en las legislaciones estatales.El acatamiento a los principios de definitividad de la instancia y cosa juzgada implica el respeto a la autonomía de las entidades federativas. Es por ello que los juzgados y tribunales establecidos al interior de ese orden deben conocer de la aplicación de normas válidas para el mismo, así como el control de la constitucionalidad de cada entidad.Las constituciones locales pueden incluir los derechos establecidos en el orden constitucional y ampliar los derechos, pero la problemática consistiría en que esa ampliación incluya instrumentos jurídicos que los hagan efectivos.El Juicio de Protección de los Derechos Humanos del Estado de Veracruz es el instrumento tutelar de los derechos humanos establecidos en la Constitución local.Existe la posibilidad de impugnar las violaciones de los derechos humanos reconocidos en la Constitución o en los tratados internacionales a través del juicio nacional o bien a través del juicio local y su justificación de existencia radica en que se permite una ampliación de derechos, pues un contenido extensivo no tendría utilidad sin un instrumento al interior que garantizara el orden local.

SECRETO Y TRANSPARENCIA: RELACIONES Y TENSIONES EN LA WEB
Authors: Durán Padilla Arturo
Published: October 2020

Secreto y transparencia pueden concebirse como términos mutuamente excluyentes aunque históricamente han coexistido sin plantear una oposición radical. Entre los griegos, la discusión acerca de los asuntos públicos no incluía a los esclavos, las mujeres ni a los extranjeros. Del mismo modo, la formación de sectas antiguas creó códigos reservados pero su expansión produjo una especie de apertura en las primeras restricciones. La secularización del mundo generó secretos reservados para prácticas específicas. Políticamente, encontramos entre otros al secreto del voto, la diplomacia y la seguridad nacional. En lo económico, involucra al secreto bancario, las patentes o derechos de propiedad. En lo religioso, sigue manteniéndose el secreto de confesión, el ritual de fe y los códigos sacramentales de la misma forma que entre las profesiones de abogados, médicos o administradores. Por tanto, es necesario entender las oposiciones del individuo con las instituciones, los grupos y al Estado frente al resto de la sociedad.
La rendición de cuentas de los servidores municipales hacia una propuesta para transparentar el artículo 155 Constitucional
Authors: Rodríguez Ávila Verónica Norma
Published: October 2020

La rendición de cuentas en materia de asignación de presupuestos, resultados e impactos en torno a los servicios públicos municipales es omisa. La revisión en los portales electrónicos de los ayuntamientos no permite conocer la aplicación de los recursos públicos en este rubro. El propósito de este ensayo es discutir acerca de la necesidad de transparentar la información presupuestaria de los servicios municipales. El procedimiento para proponer un indicador de satisfacción de información gubernamental ha partido de examinar los portales electrónicos de los 212 municipios del Estado de Veracruz, a través de una métrica experimental desarrollada por un grupo interdisciplinario de alumnos de Ciencia Política y Desarrollo Regional Sustentable de El Colegio de Veracruz en el año de 2015.

COMMUNICATION SYSTEMS FOR HIGH SPEED FLYING DEVICES WITH REPETITION CODES
Authors: Juniarto Dwi , Anwar Khoirul , Arseno Dharu
Published: October 2020

Communication systems for devices moving at high speed are suffering from error-floor due to the Doppler effect. This paper proposes a simple narrowband communication systems for high speed flying devices for critical applications such as missile and drone. To make the system simple, we consider Repetition codes and slight increase of the number of pilot symbols such that the system can predict accurately the fast-changing channel due to time-selective fading. The equalizer in this paper is designed according to the addition of the pilot symbols so that the system works at a maximum speed of 450 km/h to make successful operation for missile and drone before they are taken down by the enemy. Computer simulations are used to evaluate the performance of the proposed communication systems. The operating frequency is industrial, scientific, and medical (ISM) band, where binary phase shift keying (BPSK) modulations are used with Repetition codes being the channel coding. The bit error rate (BER) performance is evaluated under additive white Gaussian noise (AWGN) and Rayleigh fading channels. The results confirm that excellent BER performances are obtained having error-floor less than 10????4 making many applications, including image transmission, are possible, which are great for high speed flying devices even with Repetition codes and simple zero forcing (ZF) equalizer. The results of this study are expected to help the development of future communication systems for missile, drone, and airplane applications.
Robust Modified MVDR Scheme Using Chirp Signal for Direction of Arrival Estimation
Authors: Yani Kalfika , Usman Koredianto , Suratman Fiky Y
Published: October 2020

This research is about an effort to increase the robustness of the Minimum Variance Distortionless Response (MVDR) algorithm to noise by using a chirp signal for direction of arrival estimation (DoA). DoA is a part of radar capability to estimate the angle of arrival on the object under observation. The conventional MVDR as proposed by J. Capon, was designed to work with the monochromatic sinusoidal signal. Even though the conventional MVDR work on low SNR up to 0 dB, however, the conventional method does not work well if chirp signal is used instead of monochromatic sinusoidal signal. The usage of MVDR chirp signal is essential in the case of a very low SNR environment such as in long distance object detection, which is typically more than 10 km. The problem to be solved in this research is how to modify the MVDR algorithm so that it can work well on chirp signal. In this research we offer a modified MVDR algorithm by adding the matched filter and the phase detector components before the MVDR algorithm is applied. Matched filter is responsible for the timing of the chirp signal detection, and the phase detector is to estimate the time delay estimation of each chirp signal from each antenna with a reference signal, which correspond to the phases. Based on the phase estimation, sinusoidal signal is generated and fed to the MVDR algorithm. On the technical aspect, the chirp signal is sent intermittently with a duration of 100 ?s and repeated in time interval of 1 ms. The antenna sensor using an array of Uniform Linear Array (ULA) which consist of N-elements. Computer simulation shows that the modified MVDR using the chirp signal improve the robustness of the algorithm up to -30 dB, while on the other hand the classical MVDR works only up to 0 dB SNR. -30 dB of SNR is the minimum requirement of 3D Radar existing.

Authors: Pereira Roseane Lima , Da Silva Franklin Barbosa , Barbosa Rafael Saulo Santos , Augusto Carolina Rocha , Meira Joyce de Figueiredo
Published: October 2020

O objetivo deste estudo é relatar um caso clínico de remoção de um pino pré-fabricado rosqueável metálico com auxílio de magnificação por microscópio e uso de ultrassom. Paciente de 47 anos, gênero feminino, compareceu à clínica de odontologia queixando-se da insatisfação com seu sorriso. Durante a anamnese observou-se que as restaurações nos dentes 44, 45, 46 e 47 apresentavam-se insatisfatórias. Nos exames radiográficos foi possível observar lesão periapical nos dentes 44 e 47, presença de tratamentos endodônticos insatisfatórios no 44, 45, 46 e 47, e a presença de retentores intrarradiculares metálicos em todos os dentes citados. A partir dos exames, planejou-se a remoção do pino pré-fabricado do dente 45. O processo de remoção iniciou-se com isolamento absoluto e remoção do material restaurador, em seguida, com auxílio de um microscópio óptico para magnificação do campo, foi realizada a técnica de sistema integrado e simultâneo de ultrassom, em que utiliza-se duas pontas de ultrassom em vibrações opostas sobre o retentor. Após sequências de aplicação da técnica houve fratura da película de cimento e o pino foi removido. Assim, a associação da magnificação proporcionada pelo microscópio e a vibração do ultrassom foram resolutivos, pois ofereceram melhor acuidade visual e segurança no procedimento.
Diabetic dermopathy (shin spots) and diabetic retinopathy – Are they associated?
Authors: Samson Joan Felicita , Philip Mariam , Prasad Shimna Clara , Kanakamma Libu Gnanaseelan
Published: October 2020

Objectives:

Shin spots and diabetic retinopathy are considered as manifestations of diabetic microangiopathy. However, there are only a few studies about this possible association. We undertook this study to confirm a possible association between shin spots and diabetic retinopathy.

Materials and Methods:

A total of 137 patients between the ages of 40 and 70 years having diabetes mellitus of at least 5 years duration were included in the study. These patients were examined for skin and retinal changes. The study period was 6 months.

Results:

Of the 137 diabetic patients included in this study, 123 (89.8%) had shin spots. The mean age of diabetic patients with shin spots was 59.6 years. Diabetic retinopathy was seen in 83 cases (60.6%), of which 79 (95.2%) had shin spots. The mean duration of diabetes mellitus in patients with shin spots was 12.7 years and it was 8.1 years in those without shin spots. The mean duration of diabetes mellitus in patients with diabetic retinopathy was 13.6 years and it was 9.9 years in those without diabetic retinopathy. On doing regression analysis, it was found that it is the duration of diabetes that was associated with shin spots.

Limitations:

Small sample size was the limitation.

Conclusion:

Duration of diabetes mellitus is associated with the presence of dermopathy.
Prospects and challenges for an Indian dermatologist in the United Kingdom
Authors: Bali Sheerja , Rajeev Asha
Published: October 2020

The United Kingdom is a sought-after destination to gain overseas experience and long-term employment for doctors trained in India. However, for many the path is unclear. This article aims to explain the various opportunities and the steps involved in securing a job in the National Health Service (NHS) for an Indian dermatologist. The steps to obtain the General Medical Council license to practice include demonstrating competency in English and passing the Professional and Linguistic Assessments Board examinations. Once the doctor is eligible to practice, career options are working as Core Medical trainee, Staff grade and Associate Specialists and Specialty doctors (SAS) or a locum consultant. One can become a consultant in the UK without retraining in dermatology through Certificate of Eligibility for Specialist Registration. In the NHS, a dermatologist typically works for 8 h a day on the weekdays. Time is allotted for professional development through the Continuing Professional Development sessions. Doctors earn well in the UK although the cost of living is high.
Successful non-operative management for atlanto-occipital dislocation resulting in spinal cord contusion in a patient with atlanto-occipital assimilation and severe Chiari I malformation
Authors: Davis Jordan R. , Kluckman Matthew L. , Mallory Grant W. , Ritter John L.
Published: October 2020

Background:

Atlanto-occipital dislocation (AOD) is a rare, highly morbid, and highly lethal injury that results from high-energy trauma and almost universally requires operative management for satisfactory outcomes. It can be difficult to identify the severity of injury at the time of presentation, and when diagnosis is delayed outcomes worsen significantly. Anatomic anomalies of the craniovertebral junction may further complicate its detection. When such anomalies are present either singly or in combination, they are known to cause space constraints which may increase the likelihood of spinal cord injury. Given that such anomalies and AOD are rare, few examples of patients with both are reported in the literature. Furthermore, it is not clear in what way patient management may be impacted in this context.

Case Description:

We will present a unique case of an 18-year-old patient with traumatic AOD and an intact neurologic examination who was found to have atlanto-occipital assimilation (AOA), platybasia, basilar invagination, and severe Chiari I malformation, who was treated effectively with non-operative management.

Conclusion:

Our case demonstrates the successful application of a non-operative treatment strategy in a carefully selected patient with AOD in the context of AOA.
Surgical management of vertebral metastatic gastrointestinal stromal tumor: Case illustration, literature review, and pooled analysis
Authors: Lo Yu Tung , Mak David Siu Kei , Nolan Colum Patrick
Published: October 2020

Background:

Gastrointestinal stromal tumors (GISTs) very rarely metastasize to the vertebrae. Tyrosine kinase inhibitors (TKIs) confer favorable long-term survival and durable disease control for metastatic disease. Here, we reviewed a case and the literature to determine the various management options, and neurological outcomes for these patients.

Case Description:

A 63-year-old Chinese female with metastatic jejunal GIST previously treated with various TKIs presented with the left lower limb weakness and a sensory level at T10. MRI revealed a T9 vertebral body tumor with cord compression. The tumor was excised and surgical fixation was performed. She received 30Gy of fractionated adjuvant radiotherapy. She achieved near-complete neurological recovery but died 2 months later from systemic disease progression.

Conclusion:

Based on this case and a review of the literature, surgical intervention and treatment with TKIs with adjuvant RT can lead to comparable survival and neurological outcomes.
Biobased Aldehydes from Fatty Epoxides Through Thermal Cleavage of β-Hydroxy Hydroperoxides
Authors: Miguel Thomas De Dios , Vu Nam Duc , Lemaire Marc , Duguet Nicolas
Published: October 2020

The ring-opening of epoxidized methyl oleate by aqueous H2O2 has been studied using tungsten and molybdenum catalysts to form the corresponding fatty b-hydroxy hydroperoxides. It was found that tungstic acid and phosphostungstic acid gave the highest selectivities (92-93%) towards the formation of the desired products, thus limiting the formation of the corresponding fatty 1,2-diols. The optimized conditions were applied to a range of fatty epoxides to give the corresponding fatty b-hydroxy hydroperoxides with 30-80% isolated yields (8 examples). These species were fully characterized by 1H and 13C NMR, HPLC-HRMS and their stability was studied by DSC. The thermal cleavage of the b-hydroxy hydroperoxide derived from methyl oleate was studied both in batch and flow conditions. It was found that the thermal cleavage in flow conditions gave the highest selectivity towards the formation of aldehydes with limited amounts of byproducts. The aldehydes were both formed with 68% GC yield and nonanal and methyl 9-oxononanoate were isolated with 57 and 55% yield, respectively. Advantageously, the overall process does not require large excess of H2O2 and only generates water as a byproduct.
Hydroxy-bridged Active Site States of [NiFe]-Hydrogenase Unraveled by Cryogenic Vibrational Spectroscopy and DFT Computations

The catalytic mechanism of H2 conversion by [NiFe]-hydrogenase is subject of extensive research. Apart from at least four reaction intermediates of H2/H+ cycling, there is also a number of resting states, which are formed under oxidizing conditions. While not directly involved in the catalytic cycle, knowledge of their molecular structure and reactivity is important, because these states usually accumulate in the course of hydrogenase purification, and they may also play a role in vivo during hydrogenase maturation. Here, we applied low-temperature infrared (cryo-IR) and nuclear resonance vibrational spectroscopy (NRVS) to the isolated catalytic subunit, HoxC, of the heterodimeric regulatory [NiFe]-hydrogenase (RH) from Ralstonia eutropha. Cryo-IR spectroscopy revealed that the HoxC protein can be enriched in almost pure redox states suitable for NRVS investigation. NRVS analysis of the hydrogenase catalytic center is usually hampered by strong spectral contributions of the FeS clusters of the small, electron-transferring subunit. Therefore, our approach to investigate the FeS cluster-free, 57Fe labeled HoxC granted an unprecedented view onto the active site modes, including those obscured by FeS cluster-derived bands. Rationalized by density functional theory (DFT) calculations, our data allow the structural description of two hydroxy-containing resting states. Our work highlights the relevance of cryogenic vibrational spectroscopy and DFT to elucidate the structure of barely defined redox states of the [NiFe]-hydrogenase active site.

Protein microarrays have gained popularity as an attractive tool for various fields, including drug and biomarker development, and diagnostics. Thus, multiplexed binding affinity measurements in microarray format has become crucial. The preparation of microarray-based protein assays relies on precise dispensing of probe solutions to achieve efficient immobilization onto an active surface. The prohibitively high cost of equipment and the need for trained personnel to operate high complexity robotic spotters for microarray fabrication are significant detriments for researchers, especially for small laboratories with limited resources. Here, we present a low-cost, instrument-free dispensing technique by which users who are familiar with micropipetting can manually create multiplexed protein assays that show improved capture efficiency and noise level in comparison to that of the robotically spotted assays. In this study, we compare the efficiency of manually and robotically dispensed α-Lactalbumin probe spots by analyzing the binding kinetics obtained from the interaction with anti-α-Lactalbumin antibodies, using the interferometric reflectance imaging sensor platform. We show that the protein arrays prepared by micropipette manual spotting meet and exceed the performance of those prepared by state-of-the-art robotic spotters. These instrument-free protein assays have higher binding signal (~4-fold improvement) and a ~3-fold better signal-to-noise ratio (SNR) in binding curves, when compared to the data acquired by averaging of 75 robotic spots corresponding to the same effective sensor surface area. We demonstrate the potential of determining antigen-antibody binding coefficients in 24-multiplexed chip format with less than 5% measurement error.

Published: October 2020

Machine-learned ranking models have been developed for the prediction of substrate-specific cross-coupling reaction conditions. Datasets of published reactions were curated for Suzuki, Negishi, and C–N couplings, as well as Pauson–Khand reactions. String, descriptor, and graph encodings were tested as input representations, and models were trained to predict the set of conditions used in a reaction as a binary vector. Unique reagent dictionaries categorized by expert-crafted reaction roles were constructed for each dataset, leading to context-aware predictions. We find that relational graph convolutional networks and gradient-boosting machines are very effective for this learning task, and we disclose a novel reaction-level graph-attention operation in the top-performing model.

Ask what an equilibrium can do for you:Hydrolysis of pentose-1-phosphates leads to an apparent increase of the equilibrium conversion in nucleoside phosphorolysis reactions. This information can be leveraged via equilibrium thermodynamics to determine the hydrolysis kinetics of in situ generated sugar phosphates, which are known to be elusive and difficult to quantify.
Punching Above its Weight: Life Cycle Energy Accounting and Environmental Assessment of Vanadium Microalloying in Reinforcement Bar Steel

Published: October 2020

The manuscript presents a detailed analysis of embodied energy and carbon footprint reduction enabled by microalloying of steel, thereby providing a rich global perspective of the (outsized) role of chemical elements added in trace concentrations on the overall footprint of the construction industry. As such, the manuscript addresses an important and timely topic at the intersection of materials criticality, structural performance, life cycle assessment, and policy interventions.

The United Nations estimates that the worldwide energy consumption of buildings accounts for 30—40% of global energy production, underlining the importance of the judicious selection of construction materials. Much effort has focused on the use of high-strength low-alloy steels in reinforcement bars whose economy of materials use is predicated upon improved yield strengths in comparison to low-carbon steels. While microalloying is known to allow for reduced steel consumption, a sustainability analysis in terms of embodied energy and CO 2 has not thus far been performed. Here we calculate the impact of supplanting lower grade reinforcement bars with higher strength vanadium microalloyed steels on embodied energy and carbon footprint. We find that the increased strength of vanadium microalloyed steel translates into substantial material savings over mild steel thus reducing the total global fossil carbon footprint by as much as 0.385%. A more granular analysis pegs savings for China and the European Union at 1.01 and 0.19%, respectively, of their respective emissions.

The ambiphilic N-heterocyclic carbene ligand, indol-2-ylidene (IdY, A), is described. A series of indolenium precursors (2a-f) were prepared on a gram scale in good yields. Trapping experiments with elemental selenium, [RhCl(cod)]2 and CuCl lead to IdY-supported materials, respectively. Computational and spectroscopic studies revealed the ambiphilicity of IdY. The copper complexes (6) show high percent buried volume (%Vbur = 58.1) and allow for carboboration of terminal alkynes within 30 minutes as synthetically useful yields and high regioselectivity.
