Published: September 2023

White matter of the human brain is influenced by common genetic variations and shaped by neural activity-dependent experiences. Variations in microstructure of cerebral white matter across individuals and even across fiber tracts might underlie differences in cognitive capacity and vulnerabilities to mental disorders. The frontoparietal and cingulo-opercular networks of the brain constitute the central system supporting cognitive functions, and functional connectivity of these networks has been used to distinguish individuals known as “functional fingerprinting.” The frontal aslant tract (FAT) that passes through the two networks has been implicated in executive functions. However, whether FAT can be used as a “structural fingerprint” to distinguish individuals and predict an individual's cognitive function and dysfunction is unknown. Here we investigated the fingerprinting property of FAT microstructural profiles using three independent diffusion MRI datasets with repeated scans on human participants including both females and males. We found that diffusion and geometric profiles of FAT can be used to distinguish individuals with a high accuracy. Next, we demonstrated that fractional anisotropy in different FAT segments predicted distinct cognitive functions, including working memory, inhibitory control, and relational reasoning. Finally, we assessed the contribution of altered FAT microstructural profiles to cognitive dysfunction in unmedicated patients with obsessive-compulsive disorders. We found that the altered microstructure in FAT was associated with the severity of obsessive-compulsive symptoms. Collectively, our findings suggest that the microstructural profiles of FAT can identify individuals with a high accuracy and may serve as an imaging marker for predicting an individual's cognitive capacity and disease severity.SIGNIFICANCE STATEMENTThe frontoparietal network and cingulo-opercular network of the brain constitute a dual-network architecture for human cognitive functions, and functional connectivity of these two networks can be used as a “functional fingerprint” to distinguish individuals. However, the structural underpinnings of these networks subserving individual heterogeneities in their functional connectivity and cognitive ability remain unknown. We show here that the frontal aslant tract (FAT) that passes through the two networks distinguishes individuals with a high accuracy. Further, we demonstrate that the diffusion profiles of FAT predict distinct cognitive functions in healthy subjects and are associated with the clinical symptoms in patients with obsessive-compulsive disorders. Our findings suggest that the FAT may serve as a unique structural fingerprint underlying individual cognitive capability.

Purpose
The purpose of this study was to evaluate the feasibility of radiofrequency ablation (RFA) for thyroid nodules with cytological atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS, Bethesda III).

Materials and methods
A total of 28 adults presenting with 30 initial Bethesda III nodules underwent thyroid RFA at a single medical center. Thyroid nodules with Bethesda IV or V according to the second aspiration were excluded. All RFA procedures were performed using the free-hand, ‘moving-shot’ technique under local anesthesia. Clinical features and demographics, RFA details, nodule volume reduction rate (VRR), and complications were analyzed.

Results
The mean age of patients was 47.6 years, 82.1% of whom were females. Mean nodule volumes at pre-RFA, and at 6 months and 12 months post-RFA were 7.92, 2.42, and 1.25 mL, respectively, with a VRR of 77.9% at 6 months, and 87.4% at 12 months. Post-RFA complications were noted in two patients, one with transient vocal cord palsy and another with isthmus minor rupture.

Conclusion
RFA may be another safe alternative except for active surveillance or surgical excision for AUS/FLUS nodules with low-suspicion Thyroid Imaging Reporting and Data System features for patients who are unsuitable or strongly refuse surgery. Long-term results remain uncertain, thus further follow-up study is necessary.
En Busca de una Distribución más Racional y Equitativa de los Programas que se Destinan, en México, al Mejoramiento de la Calidad de la Educación Básica

Published: September 2023

Se construyó una base de datos que permitió identificar las escuelas en las que se implementaron diversos programas orientados a mejorar la calidad de la educación básica. En seguida -controlando los grados de marginalidad de las localidades en que se encontraban las escuelas- se estimó la eficacia académica de dichos programas (expresado por el aprovechamiento que obtuvieron, en promedio, los centros escolares en las que -aisladamente o en forma conjunta- aquéllos fueron implementados). Al comparar ese aprovechamiento con el que obtuvieron las “escuelas testigo” (aquéllas en las que no fue implementado programa alguno) se estimaron los puntajes marginales asociados con cada programa o combinación de los mismos. Por separado, se construyeron los costos por alumno correspondientes a cada programa -o combinación de los mismos-; los cuales fueron considerados, también, como “costos marginales” (porque eran adicionales a los costos de operación de las escuelas). Al comparar esos puntajes con los costos respectivos, se obtuvo la relación puntaje/costo. Se consideró que esa relación representaba el grado de eficiencia con la que fueron aprovechados los recursos financieros destinados al programa (o conjunto de programas) correspondientes. Se encontró que, sólo en pocas ocasiones, la eficacia de los programas coincidía con la eficiencia de los mismos. Por esta razón, se propone una regla de decisión para distribuir los programas (o sus combinaciones) entre las escuelas, aplicando un criterio de equidad.

Published: September 2023

The paper considers the present-day taxonomic and ecological diversity, spatial patterns of phytoplankton and algae on the interface of two phases: water – substratum (microphytobenthos and phytoepiphyton) in the most typical biotopes of Kaniv Reservoir in summer seasons of 2017–2022. 301 species (311 intraspecific taxa) of algae have been identified from 142 genera, 75 families, 44 orders, 15 classes and 8 phyla. At the phyla level Bacillariophyta, Chlorophyta and Cyanobacteria dominated. The highest number of species and infraspecific taxa – 143 (146) have been found in microphytobenthos. The highest diversity at the level of genera (98), families (57), orders (37), classes (11) and phyla (7) was observed for the phytoplankton. The phytoplankton was dominated by Chlorophyta and Bacillariophyta, the microphytobenthos and phytoepiphyton – by Bacillariophyta. The highest level of species similarity has been recorded between the algal communities at the interface of two phases: water – substratum, the highest dissimilarity – between phytoplankton and phytoepiphyton. According to geographic distribution cosmopolite species prevail, according to saprobity – χ-ο- and β-mesosaprobic organisms, according to salinity preferences – indifferent species, according to pH preferences – alcalifilic species. According to biotopic preference typically planktonic and eurytopic forms dominate the phytoplankton, and benthic and eurytopic forms dominate the microphytobenthos and phytoepiphyton. Comparing the present-day findings with the retrospective data has not shown any significant changes in the phytoplankton and the microphytobenthos structures. As before, Chlorophyta, Bacillariophyta and, to a lesser extent, Cyanobacteria continue to dominate in phytoplankton, and Bacillariophyta and Chlorophyta – in microphytobenthos. It is explained by natural internal processes prevailing in Kaniv Reservoir, relatively stable level of human impact, and constant algal flow from Kyiv Reservoirs and tributaries. Nowadays phytoplankton, microphytobenthos and phytoepiphyton are distinguished by high taxonomic diversity and play an important role in Kaniv Reservoir biodiversity.

AbstractIn the present work, scaffolds with gyroid TPMS geometry were obtained from a commercial resin of acrylic nature loaded with 0.5% and 1% w/V of calcium phosphate nanoparticles through DLP. The scaffolds obtained presented Young's Modulus between 300 and 400 MPa, which makes them suitable for bone applications. The surface treatment by oxygen plasma carried out on the scaffolds resulted in a notable improvement in the wettability of the surfaces, which favours cell adhesion on the surface of the materials. The in vitro bioactivity assay conducted on the resin/calcium phosphate particles composite material showed that an apatitic layer forms on the surface of the samples from the third day of exposure to simulated body fluid (SBF), indicating that the composite material has in vitro bioactive behaviour. Biological tests demonstrated that the material is not cytotoxic and favours cell adhesion and that the gyroid geometry promotes cell proliferation.

Oilfield Sidetracking-Fracturing Technology Drives out Reservoir Potential - An Economic and Effective Solution to Improve EOR of Low-Permeability Reservoir

Published: September 2023

Abstract
Ansai oilfield, located on the Loess Plateau in Northwest China, is famous for its typical low-permeability reservoirs and has been developed for more than 30 years. There are more and more flooded wells, low production wells and casing damage wells, which have become the "stumbling block" on the road of stable development. How to produce the remaining reserves more effectively? Sidetracking-fracturing in the original wellbore has become an important means to tap remaining reserves.
The recoverable reserves in this area are still large. The effectiveness of conventional stimulation measures in original wells is low, and there are new problems in drilling renewal wells. Due to the strict environmental protection regulations, the wellsite approved by local governments is limited and the cost of renewal wells is high. Developers tend to sidetrack and then fracture to restore production. There is no need to apply for new wellsites. Original wellbores are not wasted and the cost of renewal wells is saved. More importantly, fracturing network can be reconstructed to fully utilize the remaining oil and improve EOR.
3.5" wellbores were sidetracked in 5.5" wellbores. The multistage fracturing in slim hole is implemented. Sidetracking technology rebuilds new wellbore and reconstructs underground well pattern, establishing a new wellbore system for fracturing. The fine fracturing is realized by fine depicting the distribution of remaining oil and optimizing the sidetracking well type. The sidetracking holes accurately pass through the remaining oil area not touched by the original wellbores, achieving a very good effect of increasing production, and the investment cost is low. Through the implementation of sidetracking-fracturing technology, old wells are revitalized and the EOR is continuously improved. Compared with other stimulation measures, the sidetracking-fracturing technology has more obvious ability to tap the remaining oil. The biggest highlight of this technology is to make full use of the upper wellbores of long-term shutdown wells and the original surface equipment to effectively utilize the uncontrolled oil reserves of the original wells without drilling new wells.
Since 2015, more than 300 wells have been implemented, and the success rate of production increase exceeds 90%. The sidetracking-fracturing technology overcomes the constraints of environmental protection regulations, investment, site and slim hole technology in Ansai Oilfield, realizes the economic and effective development of low-permeability reservoir, and successfully improves EOR.

Abstract
For decades most proppant development efforts concentrated on developing proppants that could either cope with higher stress and deliver higher conductivity or improve proppant transport via lower density, while minimal effort was put in adding other functionalities. Lately it has been recognized that placement of proppant into the formation brings a unique opportunity of conveying new functions, additional to the primary roles of keeping the frac mechanically open and providing a conductive path for production enhancement. This approach enables reducing the total cost of ownership of addressing multiple completion, data acquisition production assurance and surveillance issues by deploying multifunctional proppants in the well initial completion.
Specialty functions can be incorporated into manmade proppants during the industrial manufacturing process, thereby exploiting the placement opportunity brought by hydraulic fracturing, gravel or frack pack completions involving proppant. These functions might include assuring flow in the production system, solving formation fines production, providing reservoir surveillance or monitoring fracture properties.
This paper reviews the latest technology developments that enable the incorporation of these functions into proppants, including how the new proppant delivered technologies permit users to cost effectively deploy additional functionalities in the initial completion of hydraulically fractured, frac-packed and gravel-packed wells. The paper will also present recent case histories of field implementations of these technologies In the Sultanate of Oman which illustrate how these high function proppants can reduce overall operating costs, enhance production and diagnose hydraulic fractures. The field implementation works on this paper is as result of joint study collaboration cross technical disciplines between operator, service company and proppant technology supplier, to find appropriate solution for reservoirs and completion challenges on various fields at Oman.
CO2 Foamed Acid Systems for High Temperature Acid Fracturing

Published: September 2023

Abstract
Foamed acid fracturing is gaining importance to maximize flowback recovery and is particularly applicable when reservoir energy is not sufficient to effectively flow back the well. Foamed acid offers additional benefits such as reduced water consumption and improved acid diversion, in addition to potential features such as retardation and deeper conductivity generation. The thermal stability of foam at high temperatures is one of the main challenges. In this paper, two distinct CO2 foamed HCl acid systems with retarded acid characteristics are developed for high-temperature applications.
The development of foam viscosity depends on the type of gas, desired foam quality characteristics, the external phase fluid viscosity as a function of the type of acid blend and strength, the corrosion inhibitor package, the foaming agent, and stabilizers. The performance of CO2 foamed acid systems was assessed by several laboratory tests characterized by compatibility, corrosion, and static foaming. The rheological properties of two retarded acid systems foamed with CO2 were measured using Fann 35 at different shear rates.
The control of acid reactivity, fluid loss, and conductivity generation are three essential aspects of acid fracturing that must be addressed for acid stimulation treatments to be successful. Overall acid reactivity, which governs the dissolution of carbonate rock, can be significantly decreased after foaming at the same acid strength and temperature. This work develops two non-viscous base acid systems for foaming applications, one based on a retarding agent and the other on an organic acid, both combined with a strong mineral acid, HCl. The effectiveness of corrosion inhibitors and intensifiers was tested on T-95 type coupons at 300°F. Static foam half-life measurements were done by generating CO2 foam in a liquid column at atmospheric conditions. The static foam half-life was measured at 3-5 min for an optimized foamed acid system with 90% foam quality. Static foaming tests were also performed using blender tests to evaluate on-site quality check. The fracture geometry and the removal of undesired fines from the fracture face are influenced by the viscous characteristics of foamed acid systems. The CO2 foamed viscosity was measured at 47-55 cp at a 511 1/s shear rate using the B1-R1 bob-rotor combination for different retarded acid systems.
Resolving Common Fracturing Issues Using Combined Perforation Imaging Diagnostics
Authors: Roberts Glyn 
Published: September 2023

Abstract
Plug failures, sub-optimal stage design and variable proppant distribution across multi-cluster stages are common issues experienced during plug and perforate hydraulic fracturing. When one or more of these problems occur production potential can be significantly reduced. This case study shows how an operator in the US succesfully applied state-of-the-art fracture diagnostic methods to identify, understand and address these problems and demonstrated improved performances for all three issues in the subsequent wells.
Selecting the right stage design is a crucial factor in the success of a fracturing operation. With three different designs being considered for use during a new development the operator used perforation erosion measurements on the initial well to evaluate how uniformly proppant was placed within each stage.
Data was acquired using a new diagnostic service combining array Ultrasound and array Video sensors. Previously considered as competing services, with users required to select one or the other, combining both technologies and simultaneously acquiring the data provided some clear benefits and improved understanding which are discussed in detail.
The combined technologies provided more comprehensive diagnostics than either sensor could deliver alone. Potential issues with missing data – due either to proppant-filled (plugged) perforations or poor optical clarity - were mitigated resulting in never before achieved levels of data completeness for both surveyed wells. This significantly improved statistical accuracy and provided unequivocal results. In the first well one of the three stage design options was clearly identified as providing better proppant distribution, with 27% higher uniformity than the second-best design. However significant low side perforation erosion was measured for all three designs and casing breaches were observed at some plug setting depths. This indicated the potential for further improvement on future wells, and a change in perforating charge type was recommended along with a review of the plug design and setting procedures. With these changes applied on the subsequent well, the expected improvements were duly delivered. This evolution of stage design was confirmed as providing the best result overall, and with a substantial improvement in uniformity than had been previously achieved in well 1. In conjunction, the revised plug setting procedures eliminated the issues at plug setting depths that had previously been witnessed.
The paper aims to provide anyone targeting improved well performance by using fracture diagnostics with up-to-date knowledge of perforation imaging methods. This will allow informed decisions to be made on how to best deploy the technologies. The case study demonstrates how these methods can be readily applied to identify and resolve common fracture treatment issues, with defining optimal stage design of particularly high value. Learnings can then be used field wide to improve proppant uniformity and ultimately production.
