Published: December 2024

Abstract
With the advancement of exploration and development, various mud logging technologies have been gradually developed. Among these technologies, light hydrocarbon logging plays a crucial role in identifying reservoir fluid properties, guiding engineering decisions, and selecting reservoirs for oil testing due to its high resolution, accuracy, and anti-interference capabilities. However, light hydrocarbon logging technology has its limitations, for its single point analysis, lengthy analysis time, and lack of timeliness. On the other hand, gas logging technology offers good continuity and timeliness. Therefore, GW-OLS online light hydrocarbon logging technology is developed by integrating the advantages of the two logging technologies. This technology can obtain real-time reservoir data, including C1-C8, a total of 15 kinds of hydrocarbon components, with good continuity, high timeliness, resolution, accuracy, strong anti-interference, and other advantages. Through the research, the online light hydrocarbon logging gas index Lg, oil index Lo, water index Lw, and other derived parameters are established, which can realize the timely and accurate identification of fluid properties during the drilling process. Currently, online light hydrocarbon logging has been applied in many oil fields such as Liaohe, Jidong, and Changqing, and verified by oil tests, with a coincidence rate of up to 81.9%, demonstrating its extremely high application and promotion value.
On estimating the effective sensitivity of a TOF-PET system for
a particular imaging task

Published: December 2024

Abstract
Comparing positron emission tomography (PET) systems which
have different features is not straightforward. To address this, we
propose to image the same object with all considered PET systems
using a fixed scan time, and reconstruct from each scan an image at
the same predefined spatial resolution. With such resolution matched
reconstructions, the images should be identical except for their
noise. Therefore, the PET system that produces the image with the
lowest variance has the best performance. An analytical model is
described to compute this variance, assuming that the PET system is
(approximately) cylindrical, the imaged object is a uniform cylinder
centered in the field of view, and the variance is only computed at
the center of the reconstructed image. The model takes into account
the solid angle covered by the detectors, the detector stopping
power, the time-of-flight (TOF) resolution, the scatter fraction and
the spatial resolution of the system, the attenuation and diameter
of the cylinder and the desired spatial resolution of the
reconstructed image. The inverse of this variance can be considered
as the effective sensitivity of the system. This effective
sensitivity can be calibrated based on the NEMA line source
sensitivity. As a performance metric for scanning long objects, the
minimum sensitivity achieved over the object is computed, with an
optimal number of bed positions and optimal overlap between
them. The influence of the spatial and TOF resolution on the
effective sensitivity is verified with simulations.

Abstract
Beam Drift Chamber (BDC) is designed to reconstruct the
trajectories of incident rare isotope beams provided by RAON (Rare
isotope Accelerator complex for ON-line experiments) into the
experimental target of LAMPS (Large Acceptance Multi-Purpose
Spectrometer). To conduct the performance test of the BDC, the
prototype BDC (pBDC) is manufactured and evaluated with the high
energy ion beams from HIMAC (Heavy Ion Medical Accelerator in Chiba)
facility in Japan. Two kinds of ion beams, 100 MeV proton, and
200 MeV/u 12C, have been utilized for this evaluation, and the
track reconstruction efficiency and position resolution have been
measured as the function of applied high voltage. This paper
introduces the construction details and presents the track
reconstruction efficiency and position resolution of pBDC.
Thermodynamic simulation of a water-injected twin-screw steam compressor
Authors: Grieb M , Brümmer A 
Published: December 2024

Abstract
Decarbonisation of industrial heating and process steam generation is crucial for the mitigation of advancing climate change. High-temperature heat pumps can meet these demands while effectively integrating with renewable energy sources, outperforming traditional heating and boiling systems, especially when operating with natural refrigerants. Since compressor efficiency is critical for the effectiveness of heat pump systems, particular care is required in compressor design and specification. Detailed thermodynamic simulations of the compressor system are indispensable in this process. The compression of fluids with a negative saturation vapour curve leads to challenging temperature increases during compression, with substantial superheating of the working fluid. In this context, a promising approach is the injection of liquid working fluid into the compressing chambers for internal cooling. This introduces new complexity to compressor simulations for heat-pump applications. In this work, a novel two-phase approach for multi-chamber model simulations of positive displacement compressors is presented. Initially, a quasi-isentropic reference process for vapour compression with internal liquid injection is introduced and efficiency ratings are derived. Furthermore, the simulation process is described in detail, and comprehensive thermodynamic simulations of a water-injected twin-screw steam compressor are carried out.
Design of toothed belt driven screw vacuum pumps
Authors: Müller R , Dreifert T , Hellmig A 
Published: December 2024

Abstract
Most screw vacuum pumps use oil-lubricated gears for timing of the rotors. An alternative is a toothed belt to drive and synchronise the screw rotors. In combination with grease-lubricated bearings this drive concept allows the design of completely oil-free pumps. However, belts are less accurate in terms of timing, hence the design of efficient pumps is challenging. In this paper, the development of a new series of belt driven dry screw vacuum pumps is discussed. It covers the overall pump concept including cooling system, material selection and noise damping. Particular attention is paid to the design of the screw rotors with respect to the properties of the belt drive. It is shown that the disadvantage of the inaccurate timing and the need for wide rotor to rotor clearance can be overcome with a high number of wraps. Furthermore, it gives insight to applications and practical field experience.
Predicting the fracture forming limit of 5754-O aluminum alloy by finite element simulation
Authors: Yan Bin , Zhang Guocheng , Liu Xiaoli , Yin Xiaolin 
Published: December 2024

Abstract
Aluminum alloy has the advantages of low specific gravity, easy processing and good welding performance, so it is widely used on automobiles to achieve lightweighting. Forming limit diagram (FLD) is the most intuitive method for evaluating and analyzing the forming performance of aluminum alloys. Standard forming limit tests are complex and costly. To simplify test procedures of the formability for 5754-O aluminum alloys, three tests including uniaxial tensile, deep drawn cup and dome stretching tests were established through ABAQUS finite element software. The principal and secondary strain values at the time of fracture were extracted to construct the forming limit curve at fracture (FLCF). In order to verify the accuracy of the simulation results, corresponding experiments were conducted. The finite element simulation results match the experimental results, thereby verifying the accuracy of the finite element simulation. The method presented in this paper enables quick prediction of the formability of aluminum alloy.
Can political connection promote policy advocacy of social work organizations in China?
Authors: Xu Yang , Ren Fengjia , Wu Wenzhao , Enjian Wang 
Published: December 2024

Abstract
Policy advocacy is an important function and service content of social work organizations. The role of political connection in policy advocacy by social work organizations is controversial and has not been fully discussed in China. The study examined the association between political connection and policy advocacy and the moderating effects of executives’ specialization, among social work organizations in China. Based on a sample of 687 organizations and the Oprobit Regression Model method, the findings confirmed that political connection was positively related to social work organizations’ policy advocacy. Also, the positive effect between political connection and policy advocacy was moderated by executives’ specialization. Specifically, the positive effect between political connection and policy advocacy was more substantial when executives of social work organizations had a higher level of specialization. The results of this study enrich the empirical research on social work policy practice and provide a reference for the debate on political connection and policy advocacy.
Free Trade Agreements and the movement of business people
Authors: Mayer Thierry , Rapoport Hillel , Umana-Dajud Camilo 
Published: December 2024

Abstract
Using provisions to ease the movement of business visitors in trade agreements, we show that removing barriers to the movement of business people promotes trade. We document the increasing complexity of Free Trade Agreements (FTAs) and develop an algorithm that combines machine learning and text analysis techniques to examine the content of FTAs. We use the algorithm to determine which FTAs include provisions to facilitate the movement of business people and whether these are included in dispute settlement mechanisms. We show that provisions facilitating business travel are effective in promoting them and eventually increase bilateral trade flows. The paper provides (indirect) evidence of the role of face-to-face interaction on aggregate bilateral trade flows.

Published: December 2024

Background:
Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Despite advancements in surgical techniques and perioperative care, patient outcomes vary significantly across healthcare institutions. Textbook outcome (TO), a composite metric representing an ideal postoperative course, has been proposed as a standard for assessing the quality of surgical care in CRC. However, its impact on patient outcomes remains underexplored, particularly across diverse clinical settings.

Objective:
This study aims to explore surgeons’ adherence to TO criteria and identify patient-specific and procedural risk factors associated with TO failure. The study will also evaluate TO as a quality metric in CRC surgery, examining its association with short-term and long-term clinical outcomes in a multicenter cohort.

Methods:
This multicenter, retrospective cohort study will include all adult patients undergoing CRC resection between 1 January 2022 and 31 December 2024 across multiple centers in Italy, on behalf of the Italian Surgical Association (ACOI, Associazione Chirurghi Ospedalieri Italiani). The study will collect and analyze demographic, clinical, and surgical data to determine TO incidence and its association with key outcomes, including radical resection, 30-day mortality, morbidity, no reintervention, no ostomy placement, and a hospital stay of 14 days or less.

Conclusions:
This study will offer valuable insights into the utility of TO as a metric for evaluating the quality of care in CRC surgery. These findings may inform future guidelines and policies aimed at improving CRC surgical outcomes.
Absorbable gelatin sponge as an intrascleral buckle in rabbits: a pilot study
Authors: Zhou Yan , Lin Shiqun , Xiao Xingyu , Chen Youxin , Chen Zhe , Dai Rongping 
Published: December 2024

Purpose:
This study aimed to evaluate the efficacy and safety of using an absorbable gelatin sponge as an intrascleral buckle in rabbit eyes; it also monitored degradation of the gelatin sponge over time.

Methods:
Ten New Zealand white rabbits underwent surgery to implant an absorbable gelatin sponge as an intrascleral buckle. Weekly ophthalmic examinations were conducted before and after the procedure until the implant was fully absorbed. Assessments included external eye and fundus examinations, color fundus imaging, and optical coherence tomography. Safety and efficacy were determined by comparing pre-operative and post-operative conditions.

Results:
The surgery was successfully completed in 12 of 20 eyes, yielding favorable postoperative outcomes. Eight eyes were excluded due to issues with scleral tunneling, including accidental penetration, suprachoroidal implantation of the sponge, and choroidal excavation, resulting in a success rate of 60%. The indentation produced by the gelatin sponge implant progressively decreased, entirely disappearing within 2 weeks. No complications, such as retinal or choroidal hemorrhage or detachment, were observed.

Conclusion:
Intrascleral implantation of absorbable gelatin sponge was safe and effective for scleral buckling in rabbits, demonstrating favorable biodegradation characteristics.
Evaluation of Foveal Hypoplasia in Children with a History of Retinopathy of Prematurity
Authors: Çelik Gökhan , Oto Bilge Batu , Kızılay Osman , Gunay Murat 
Published: December 2024

Purpose:
To evaluate the foveal development in patients diagnosed with retinopathy of prematurity (ROP) and to evaluate whether foveal development was affected by treatment in ROP patients.

Methods:
This cross-sectional study included patients with a history of ROP. Foveal development was compared between eyes with spontaneous regression and treated eyes. Additionally, gestational age, birth weight, ROP zone and stage, and postmenstrual gestational age at the time of treatment, were evaluated. The final visual acuity was analyzed according to the foveal hypoplasia (FH) severity.

Results:
This study included 166 eyes from 83 patients. Foveal development was significantly different among the treatment and spontaneous regression groups, and FH was more severe in the treatment group. The prevalence of normal foveal development was higher in the spontaneous regression group than in the treatment groups. This suggests that ROP treatment may induce morphological alterations during foveal development. Gestational age, postmenstrual age at the time of treatment, ROP stage, and ROP zone were correlated with FH severity. Visual acuity was not affected by mild FH, and 88.5% of the patients had a visual acuity of LogMAR 0.

Conclusion:
Early stage foveal development is not significantly disrupted in patients with ROP, and patients with ROP show no significant visual disturbance associated with FH. However,eyes treated for ROP either with laser photocoagulation or intravitreal anti-vascular endothelial growth factor demonstrated more severe hypoplasia compared to that with spontaneous regression.

Published: December 2024

Objectives:
This study aimed to develop machine learning (ML) prediction models for identifying bloodstream infection (BSI) and septic shock (SS) in pediatric patients with cancer who presenting febrile neutropenia (FN) at emergency department (ED) visit.

Materials and Methods:
A retrospective study was conducted on patients, younger than 18 years of age, who visited a tertiary university-affiliated hospital ED due to FN between January 2004 and August 2022. ML models, based on XGBoost, were developed for BSI and SS prediction.

Results:
After applying the exclusion criteria, we identified 4423 FN events during the study period. We identified 195 (4.4%) BSI and 107 (2.4%) SS events. The BSI and SS models demonstrated promising performance, with area under the receiver operating characteristic curve values of 0.87 and 0.88, respectively, which were superior to those of the logistic regression models. Clinical features, including body temperature, some laboratory results, vital signs, and diagnosis of acute myeloblastic leukemia were identified as significant predictors.

Conclusions:
The ML-based prediction models, which use data obtainable at ED visits may be valuable tools for ED physicians to predict BSI or SS.

Abstract

Objective
To examine the long-term perioperative changes in lumbar bone density, muscle size and fatty atrophy, and facet degeneration after transfemoral amputation (TFA).

Design
All patients who underwent TFA at an academic center between 2002-2022 were retrospectively identified. Patients were required to have preoperative and postoperative CT (>1 year) and regularly utilize a prosthesis. Preoperative to postoperative changes in lumbar and muscular vertebral Hounsfield units (HU), facet degeneration, and bilateral psoas, quadratus lumborum, multifidus, and erector spinae cross-sectional area (CSA) were determined.

Results
A total of 42 patients met the inclusion criteria. There were significant preoperative to postoperative decreases in HUs in the L1 and L3 vertebral bodies were -17.69 and -25.35, respectively. There were significant pre- to post-operative increases in L4-5 and L5-S1 facet degeneration grade. There were significant pre- to post-operative decreases in amputated side psoas HU and CSA. There were also significant pre- to post-operative HU decreases in the bilateral multifidus and erector spinae muscles, where the changes were more pronounced on the contralateral side.

Conclusion
TFA was associated with progression of lumbar facet degeneration, small scale decreases in lumbar bone quality, amputated side psoas atrophy, and bilateral fatty infiltration of the multifidus and erector spinae.
The Effectiveness of Early Treatment With Intense Pulsed Light Combined With Fractional Erbium Laser in Preventing Post-traumatic Hypertrophic Scar Formation
Authors: Dai Qiang , Cheng Lin , Wang Cheng 
Published: December 2024

Background:
Once scars form and begin to proliferate, treatment becomes challenging. Traditional methods of scar treatment often provide suboptimal results. Therefore, early intervention has become widely accepted, with a focus on prevention during the wound-healing phase rather than later treatment. Here, the authors evaluate the effectiveness of early treatment with intense pulsed light (IPL) combined with fractional erbium laser in preventing the formation of post-traumatic hypertrophic scars.

Methods:
A total of 120 patients who underwent emergency cosmetic suture surgery for facial trauma between January 2019 and December 2021 were selected for the study. The control group received conventional antiscar therapy (pressure therapy or antiscar medication), while the observation group received IPL combined with fractional erbium laser in addition to the conventional treatment. The specific treatment doses were adjusted based on the patient’s age, scar color, texture, and thickness. A treatment course consisted of 3 to 5 sessions, with 4-week intervals between treatments. Follow-up was conducted within 1 year after treatment to assess the improvement in scar appearance before and after therapy.

Results:
After IPL combined with fractional erbium laser treatment, patients in the observation group showed significantly lower scores in color, thickness, vascular distribution, softness, and total scores on the Vancouver Scar Scale (VSS) compared with the control group. During the follow-up, 3 complications were observed: 2 cases of skin blisters and 1 case of pigmentation. No immediate skin lesions, depigmentation, infections, ulcers, or other adverse reactions were reported.

Conclusions:
For patients with early-stage superficial scars following trauma surgery, early treatment with IPL combined with fractional erbium laser not only leads to significant improvements in appearance and effectively prevents hypertrophic scar formation but also promotes rapid recovery with few complications. This approach has clinical value.
