Early identification of hereditary cancer predisposition in adolescents and young adults represents a unique opportunity to target cancer prevention and improve survival in a population at risk for adverse health outcomes. However, adolescents and young adults face challenges unique to their stage of life that can undermine their transition from pediatric to adult healthcare and lead to interruptions in preventative care. The purpose of this study was to understand expert perspectives on factors relevant to designing and implementing a transition clinic for adolescents and young adults with hereditary cancer predisposition. We used qualitative methods informed by human-centered design and implementation science to identify implementation considerations rooted in clinician experience. To understand clinic design and clinician experience at Geisinger transition clinics, we conducted a contextual inquiry using clinic observations and follow-up interviews of clinicians. To learn about designing and implementing a transition program, we also conducted in-depth interviews with national transition experts actively involved in developing, implementing, or participating in transition clinics around the United States. The contextual inquiry resulted in three diagrams depicting the following common elements of transition clinics at our institution: relationship building with patients, care coordination, stepwise transition education, communication between providers, and a sustainable clinic home. Interviews were analyzed deductively using thematic analysis to learn clinician perspectives about program implementation specific to each domain of the RE-AIM theoretical framework: reach, effectiveness, adoption, implementation, and maintenance.

Published: January 2025

Trichinella spiralis (T. spiralis) is a highly pathogenic zoonotic nematode that poses significant public health risks and causes substantial economic losses. Understanding its invasion mechanisms is crucial. This study explored how the serine protease inhibitors (SPIs) secreted by T. spiralis affect the host’s intestinal epithelial barrier. Furthermore, the effects of T. spiralis infection on the jejunal barrier function in mice were investigated. The histopathological analysis indicated significant damage to the jejunum, which peaked at day 7 post-infection (dpi). The results of RT-qPCR and western blotting revealed marked reductions in tight junction proteins (ZO-1, occludin, claudin-3), mucins (MUC-1, MUC-2), and anti-inflammatory cytokines (TGF-β, IL-10) from 1 to 15 dpi. There was also increased expression of Toll-like receptors (TLR-1, TLR-2, TLR-4) and pro-inflammatory cytokines (TNF-α, IL-1β). Recombinant SPIs (rKaSPI, rAdSPI) were purified, co-cultured with intestinal epithelial cells (IPECs), and used in mouse models. The protein expression changes in IPECs and mice were consistent with those in T. spiralis-infected tissues. Both SPIs caused the down-regulation of ZO-1, occludin, claudin-3, MUC-1, MUC-2, TGF-β, and IL-10 while up-regulating TLR-4 and pro-inflammatory cytokines. As a result, the intestinal barrier was disrupted, and inflammation was exacerbated. Notably, rAdSPI had a more pronounced effect. In summary, T. spiralis infection caused significant jejunal damage and disrupted the intestinal barrier. T. spiralis-secreted SPIs, especially serpin-type serine protease inhibitors (AdSPI), were pivotal in facilitating invasion by compromising the host’s intestinal barrier and promoting inflammation. This study provides insights into T. spiralis invasion mechanisms and the potential targets for trichinellosis prevention and control.

Published: January 2025

Purpose

To evaluate access site adverse events following ClotTriever-mediated large-bore mechanical thrombectomy via small upper extremity deep veins (< 6-mm).

Materials and methods

Twenty patients, including 24 upper extremity venous access sites, underwent ClotTriever-mediated large-bore thrombectomy of the upper extremity and thoracic central veins for symptomatic deep vein obstruction unresponsive to anticoagulation. Patients without follow-up venous duplex examinations (n = 3) were excluded. Patients who had > 6-mm diameter veins accessed (n = 3) were excluded. Temporary purse-string sutures and manual pressure were used for access site hemostasis in all patients. Vein access site and diameter, technical success (defined as placement of the 13.5-French ClotTriever sheath followed by thrombectomy), and early (< 30-days) and late (> 30-days) access site-related adverse events (according to the Adverse Event Classification by the Society of Interventional Radiology criteria) were recorded.

Results

Fourteen patients (8 males, 6 females; mean age 51.7 ± 13.6 years) comprising 16 upper extremity venous access sites were included in this study. Access sites included: right brachial (n = 7), left brachial (n = 5), and bilateral brachial (n = 2) veins. The mean access site diameter was 4.3-mm ± 0.67-mm. Technical success was achieved via all access sites. Six (42.9%) patients underwent stent reconstruction following thrombectomy through the same accesses. After the procedure, all purse-string sutures were removed within 24 h. Three (21.4%) patients experienced small access site hematomas that did not require transfusion, intervention, or prolonged hospitalization. Initial follow-up venous duplex ultrasounds were performed at 29.3 ± 21.7 days following intervention. The mean follow-up interval to the second and third venous duplex ultrasounds were 124.3 ± 64-days and 225.1 ± 80.1 days, respectively. One (7.1%) patient developed right arm swelling six days after the procedure and was found to have thrombosis of the previously accessed right brachial vein. No other clinically or sonographically significant access site adverse events were observed.

Conclusion

ClotTriever-mediated large-bore thrombectomy via small upper extremity veins is safe with minimal access site adverse events.

Context

Guidelines for use of injectable estradiol esters (valerate [EV] and cypionate [EC]) among transgender and gender-diverse (TGD) individuals designated male at birth vary considerably, with many providers noting supraphysiologic serum estradiol concentrations based on current dosing recommendations.

Objectives

This work aimed to 1. determine the dose of injectable estradiol (subcutaneous [SC] and intramuscular [IM]) needed to reach guideline-recommended estradiol concentrations for TGD adults using EC/EV; 2. describe the relationship between estradiol concentration relative to timing/dose of last estradiol injection and other covariates; and 3. determine dosing differences between IM/SC EV/EC.

Methods

A cross-sectional retrospective study was conducted across 6 US medical centers including TGD adults on same-dose injectable estradiol for more than 75 days, with confirmed timing of estradiol concentration relative to last injection, from January 1, 2019 to December 31, 2023. Descriptive statistics were used to describe patient characteristics and weighted linear mixed models to evaluate relationship between various covariates and estradiol concentration.

Results

Data from 562 patients were included. Among those injecting every 7 days who reached the guideline-recommended estradiol concentration (n = 131, 27.5%), the median estradiol dose was 4.0 mg (interquartile range, 3.0-5.0 mg). Among all patients, the majority reached supraphysiologic estradiol concentrations (>200 pg/mL [>734 pmol/L]) while dose and timing in the injection cycle were significant covariates for the estradiol concentration. There were no significant dosing differences between IM/SC EV/EC.

Conclusion

Injectable estradiol esters effectively reach guideline-recommended estradiol concentrations but at lower doses than previously recommended. Estradiol concentrations are best interpreted relative to timing of last injection. Route of administration and type of ester do not significantly affect estradiol concentrations.

Published: January 2025

Obstructive sleep apnoea (OSA) is a prevalent disorder characterized by repeated episodes of partial or complete upper airway collapse during sleep, resulting in intermittent hypoxia, hypercapnia, and sleep fragmentation. Common in middle-aged and older adults, its pathogenesis is multifactorial, encompassing obesity, craniofacial abnormalities, altered upper airway muscle function, pharyngeal neuropathy, and fluid redistribution to the neck. These episodes trigger sympathetic activation, oxidative stress, and systemic inflammation, contributing to daytime sleepiness, road traffic accidents, and a spectrum of cardiovascular and metabolic comorbidities such as hypertension, arrhythmias, coronary artery disease, stroke, and diabetes mellitus. The efficacy of therapy in reversing chronic sequelae remains uncertain. Continuous positive airway pressure (CPAP) is the first-line treatment in severe cases, although patient adherence varies between 60–70%. Alternative modalities, including bi-level positive airway pressure, adaptive servo-ventilation, oral appliances, and surgical interventions, may be employed. Weight reduction and combined treatment strategies hold promise but require validation in well-designed randomized controlled trials.

Published: January 2025

Hypertensive crisis is a medical emergency that requires urgent pharmacological intervention to prevent organ damage. The pathogenesis of this condition is often linked to excessive sympathetic nervous system activation resulting from a strong stress response. Benzodiazepines, as a class of drugs with anxiolytic and sedative effects mediated through GABA-A receptor modulation, can effectively target the underlying cause of a sudden rise in blood pressure while indirectly contributing to its reduction. This study presents a literature review on the use of benzodiazepines in the treatment of hypertensive crises, with a focus on their mechanisms of action and the limitations associated with their use. The analysis indicates that benzodiazepines, in specific patient groups, can effectively reduce psychological stress and facilitate hemodynamic stabilization. However, the potential risk of adverse effects, such as respiratory depression, must be considered. Benzodiazepines should be used with caution as a therapeutic option in hypertensive crisis management.

Published: January 2025

Endometriosis is a condition characterized by the presence of endometrial tissue in ectopic locations outside the gynecological organs. Thoracic endometriosis (TE) is a rare and underdiagnosed condition characterized by the presence of endometrial-like tissue in the thoracic cavity, leading to cyclical respiratory symptoms. TE is often misdiagnosed or overlooked, primarily due to its nonspecific symptoms. Advancements in imaging techniques and biomarkers research are promising in improving the diagnosis of TE. High-resolution imaging modalities, such as high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI), provide detailed visualization of pleural and pulmonary lesions and leverage hormonal responsiveness for dynamic imaging during the menstrual cycle. The identification of novel biomarkers, such as cystatin C and circulating microRNAs, highlights the potential for non-invasive diagnostic tools that can stratify patients based on disease severity and guide personalized treatment strategies. Early diagnosis and treatment of thoracic endometriosis are crucial to prevent severe complications such as recurrent pneumothorax, pleural adhesions, and progressive lung damage. Timely intervention also reduces the burden of chronic pain and improves quality of life, enabling more effective management of this underdiagnosed condition. The aim of this paper is to explore current diagnostic possibilities for TE, particularly through the lens of advanced diagnostic innovations, and assess their potential to improve outcomes for patients with this complex condition.

Authors: Miklis Paweł , Pniak Michał , Mawlichanów Maciej , Różycki Adrian , Wojtczak Marta , Szerej Krzysztof , Ciesielska Aleksandra , Myśliwiec Natalia , Sieradzka Aleksandra , Kot Alicja
Published: January 2025

Introduction: Small intestinal cancer is a rare form of cancer affecting the duodenum, jejunum, or ileum. Its incidence is increasing, although it is less commonly diagnosed than colorectal cancers. Understanding risk factors is crucial for early detection and prevention. These factors include non-modifiable ones like sex, race, age, and genetic conditions, as well as modifiable factors like diet, alcohol, smoking, and obesity.
Materials and Methods: A search of PubMed with the keywords "small intestine cancer" and "risk factors" identified 928 articles. After review, 48 publications and one textbook, were included.
Results: Small intestine cancer is more common in men and African Americans. Genetic conditions such as Lynch syndrome, Familial Adenomatous Polyposis (FAP), Peutz-Jeghers syndrome (PJS), and Multiple Endocrine Neoplasia (MEN1) significantly increase the risk. Chronic conditions like Crohn’s disease and celiac disease also increase risk. Diets high in red meats, processed foods, and animal fats, are linked to higher risk.
Discussion: Age and sex are key non-modifiable risk factors, with risk increasing with age, particularly over 60. Genetic conditions like Lynch syndrome, FAP, and PJS are major contributors. Chronic inflammatory diseases such as Crohn’s and celiac disease raise risk. Diets rich in animal fats, processed meats, and smoking contribute to higher risks, as does obesity. Healthy diet, quitting smoking, and maintaining a healthy weight, may reduce risk.
Conclusion: Genetic mutations, such as those in Lynch syndrome, FAP, and PJS, are significant risk factors, while lifestyle factors like diet, smoking, and obesity also play a role. Increased surveillance for individuals with genetic predispositions or inflammatory conditions may allow for earlier detection. Despite limited data, a balanced diet, weight management, and avoiding smoking may help reduce risk. Further research is needed to improve prevention strategies.

Introduction:Obesity rates have risen sharply in recent decades, with one in eight people worldwide living with obesity in 2022. This has driven interest in the search for effective and sustainable dietary strategies. Intermittent fasting (IF), which alternates periods of eating and fasting, has gained considerable attention as a tool for weight management and overall health improvement. Unlike traditional calorie-restricted diets, IF’s simplicity and flexibility make it more accessible, potentially increasing adherence and long-term sustainability.
Purpose:This study reviews current knowledge on IF, evaluating its physiological mechanisms, health benefits, risks, and long-term implications. It focuses on weight management, glucose metabolism, cardiovascular health, cognitive function, circadian rhythm, and sports performance, while addressing challenges related to safety and sustainability.
Materials and Methods:This study reviews existing literature, including clinical trials, meta-analyses, and observational studies. It compares IF protocols such as alternate-day fasting (ADF), the 5:2 diet, and time-restricted eating (TRE), emphasizing physiological effects and practical implications.

Conclusion:Intermittent fasting represents a promising dietary intervention with wide-ranging health benefits, from weight management to improved metabolic and cognitive health. However, challenges such as nutritional deficiencies, risks of hypoglycemia, and limited long-term data highlight the need for personalized approaches and further investigation. Future research should prioritize large-scale, long-term studies to refine fasting protocols and ensure safety and effectiveness across diverse populations. By addressing these gaps, IF could evolve into a sustainable, evidence-based strategy for improving global health outcomes.

Authors: Wirth Marissa , Etingen Bella , Hogan Timothy P , Smith Bridget M , Tarlov Elizabeth , Stroupe Kevin , Kartje Rebecca , Weaver Frances M
Published: January 2025

Objective:

The Veterans Health Administration (VHA) recently piloted the implementation of the TeleWound Practice Program (TWP), which provides interprofessional wound care to Veterans remotely. We assessed the perceptions of Veterans and healthcare team members (HCTMs), and their experiences with the TWP.

Method:

We surveyed Veterans from four VHA medical centres who had received at least one TWP visit between 1 May 2020 and 31 May 2021, and HCTMs associated with any TWP encounter between 1 September 2019 and 31 March 2021. Survey data were summarised using descriptive statistics and open-ended question responses were analysed using thematic coding.

Results:

Out of 534 Veterans approached, 194 completed the survey (a 36% response rate). Most were interested in continuing to use TeleWound care (66%), felt more motivated to participate in their wound care due to the TWP (70%), and reported reductions in travel distance (81%) and cost (81%) related to wound care. Of the 32 HCTMs approached, 19 completed the TWP survey (a 59% response rate). Respondents indicated that the TWP improved their own professional decision-making skills (82%) and supported Veterans to take a more active role in their health (100%). Challenges included insufficient training for HTCMs, lack of stakeholder buy-in, and logistical and technical issues. Suggestions for improvement related to equipment, additional training and dedicated TWP staff.

Conclusion:

In this study, the Veterans were satisfied with the TWP and were more motivated to engage in wound self-management after receiving care through the TWP. HCTMs also perceived the TWP as beneficial to Veterans. However, additional efforts are needed to address barriers to TWP implementation across the VHA system of care.
The provision of wound care and management in a community healthcare setting: an exploratory study
Authors: Skerritt Louise , Gooney Martin , Sheahan Linda
Published: January 2025

Objective:

Wound management can be costly and challenging to the health services' scarce resources. Information regarding the number of wounds in a community care setting and their associated aetiology will provide nurses and nurse managers with an insight into the specific needs of these clients with wounds and highlight areas where care or services can be improved or further developed. This research aimed to establish the prevalence and aetiology of wounds, the current delivery of wound care, wound documentation and referral pathways in an Irish community care setting.

Method:

A retrospective chart review was carried out on all clients in the community care area who received wound care from the Public Health Nursing Service over a specified one-year period.

Results:

A total of 331 individuals were identified as having wounds, and nearly half presented with more than one wound, equating to 632 wounds in total (point prevalence (PP)=0.46%). A total of 56% (n=186; PP=0.14%) had leg ulcers (LUs), 18% (n=58; PP=0.04%) had pressure ulcers (PUs), 15% (n=49; PP=0.04%) had developed a diabetic foot ulcer (DFUs) and a further 11% (n=38; PP=0.03%) had wounds of other aetiologies. The mean duration of wounds was 11.37 months. Comorbidities were present in 99% (n=327) of clients with wounds, with cardiovascular disease observed in 87% (n=288) of clients and diabetes in 45% (n=148). Nursing wound-related concerns resulted in 52% (n=171) of clients receiving antibiotics, with 71% (n=121) being prescribed more than one dose. As many as 61% (n=104) of clients prescribed antibiotics did not have completed documentation to demonstrate a suspected wound infection. It was established that 16% of the Public Health Nursing Service's active caseload was made up of clients with wounds and the management of these wounds accounted for 67% of nursing time, equating to 28 full-time community nurses.

Conclusion:

This study has identified that people with chronic (hard-to-heal) wounds often present with more than one chronic disease, which may negatively influence the wound's healing trajectory, lengthening its duration. The criteria for onward referral for suspected wound infections have been examined and resulted in large numbers of poorly documented wound assessments, leading to a high reliance on the use of oral antibiotics as commonplace for the management of hard-to-heal wounds. Hard-to-heal wounds, such as lower LUs, PUs and DFUs, are either caused or significantly affected by the presence of underlying comorbidities. Therefore, aligning the prevention and management of these burdensome wounds with National Clinical Programmes will deliver efficient, cost-effective, holistic quality care to clients in Irish community healthcare settings.

Difficulty removing a totally implantable venous access port: A case report
Authors: Chen Jing , Tang Mu , Han Qin-Yuan , Tang Lei , Yu Teng-Hua , Zhao Yan-Ping , He Chong-Wu
Published: January 2025

BACKGROUND

This case report examines the challenges associated with removing a totally implantable venous access port (TIVAP) used for long-term chemotherapy in a patient with breast cancer. Prolonged use of TIVAPs can result in complications such as catheter kinking, thrombosis, and adhesions between the catheter and surrounding tissues, potentially complicating their removal.

CASE SUMMARY

A breast cancer patient with bone metastasis presented with difficulty aspirating blood from a TIVAP that had been placed in the right internal jugular vein for 3 years. Initial removal attempts at the Department of Venous Access Center were unsuccessful, likely due to adhesions, necessitating a subsequent successful catheter extraction in a hybrid operating room. Imaging revealed no abnormalities, and the catheter was removed using a mosquito clamp to detach it from surrounding tissues.

CONCLUSION

This case highlights the challenges of removing TIVAPs inserted via the internal jugular vein, particularly when the catheter traverses the sternocleidomastoid muscle. Repeated neck movements might lead to significant adhesions around the catheter, complicating its removal. Careful consideration should be given during catheter placement to avoid muscle-related adhesions and facilitate smoother extraction in long-term use.

Authors: Nong Xi-Feng , Cao Xiao , Tan Xing-Lin , Jing Li-Yan , Liu Hao
Published: January 2025

BACKGROUND

Percheron acute artery occlusion is a rare type of acute cerebral infarction.

CASE SUMMARY

An elderly male presented with sudden-onset near-memory and sensory impairments for 5 days. Upon admission, based on symptoms, signs, magnetic resonance imaging, and computed tomography findings, a diagnosis of Percheron syndrome was made. Subsequently, anti-platelet therapy, lipid-lowering treatment, cerebral circulation enhancement (such as the administration of calcium channel blockers to improve cerebral blood flow), and neurotrophic support (such as the use of drugs like citicoline to protect nerve cells) were immediately implemented, along with additional symptomatic treatments. The patient’s symptoms were alleviated, following which he was discharged.

CONCLUSION

The diagnosis of acute occlusion of the Percheron artery requires rich clinical expertise and accurate imaging tools. Timely intervention and effective follow-up hold significant implications for optimizing patient recovery.
Life-threatening bleeding caused by artery pseudoaneurysm after endoscopic procedure successfully treated by artery embolization
Authors: Pérez-Holanda Sergio
Published: January 2025

The Kakinuma et al ’s case report shows that non-pregnancy-related arterial pseudoaneurysm is a relatively rare, little known by some gynecologists, endoscopists, surgeons or radiologists, which can cause massive bleeding. Arterial pseudoaneurysm is a condition in which the wall of a blood vessel collapses due to some invasive event, and the resulting leaked blood is engulfed by soft tissues, forming a cavity that is in communication with the vessel. It is a potentially life-threatening complication that could occurs after some deliveries and some gynecological invasive procedures. Remarkably, an undetermined percentage of pseudoaneurysms are asymptomatic, and in an asymptomatic patient it is difficult to predict the risk of haemorrhage and the attitude to follow, which depends on several factors, such as, the size and location of the vessel involved, changes in the size of the pseudoaneurysm, or the available therapeutic resources to be offered to patients, among others circumstances. The management of abdominal arterial pseudoaneurysm does not have consistent scientific evidence, but it seems that, regardless of the associated circumstances, the pseudoaneurysm could be treated at least initially, and mainly, through endovascular procedures, as done by Kakinuma et al .
Schur stability of matrix segment via bialternate product
Authors: Yilmaz Serife
Published: January 2025

In this study, the problem of robust Schur stability of $n\times n$ dimensional matrix segments by using the bialternate product of matrices is considered. It is shown that the problem can be reduced to the existence of negative eigenvalues of two of three specially constructed matrices and the existence of eigenvalues belonging to the interval $[1,\infty)$ of the third matrix. A necessary and sufficient condition is given for the convex combinations of two stable matrices with rank one difference to be robust Schur stable. It is shown that the robust stability of the convex hull of a finite number of matrices, where the difference between any two matrices has a rank of 1, is equivalent to the robust stability of the segments formed by these matrices. Examples of applying the obtained results are given.

Authors: Zheng Junhao , Wang Zhengpeng , Liu Binhui , Gao Huaqiang , Chen Xiaoming
Published: January 2025

In this brief paper, an improved method of separate amplitude and phase interpolations is presented for the mid-field phased array calibration system. Since the amplitude is relatively continuous and the phase suffers from phase wrapping, the proposed method uses linear and phase-unwrapping natural neighbor interpolation methods to reconstruct the amplitude and phase matrices, respectively. When compared with the existing work, the proposed method is more accurate under the cost-effective over-the-air testing environment.

Authors: Li Kun , Li Zijie , Liu Xiaorui , Li Shandong , Qu Xiaoyun , Yang Zhiqun , Zong Wei-hua
Published: January 2025

In this article, a Vivaldi antenna with broad bandwidth and high gain is proposed. The proposed antenna consists of a coplanar Vivaldi antenna (CVA) configuration etched with two rhombus slots at both sides of the radiation arm to improve bandwidth and gain at the low frequencies as well as maintaining antenna miniaturization. A compact broadband metasurface is loaded in the dielectric region between the two exponentially tapered lines to improve radiation performance in a wide frequency range without increasing antenna size. The antenna has been fabricated and measured, obtaining 1.27-9.4 GHz bandwidth covering L/S/C/X and ultra-wideband (UWB) lower bands. The measured gain ranges from 3 dBi to 9.67 dBi. With a miniaturized size of 100×100×1 mm3, good directional radiation pattern and high gain in the whole working band, the proposed antenna is a good candidate for the applications in multi-band coverage systems.

Authors: Bai Xue , Hou Yanjiao , Xu Leijun , Chen Jianfeng , Kong Yiyang
Published: January 2025

This paper proposes a one-to-multiple RF wireless power transmission (WPT) system that uses multi-mode phased array technology to control beamforming. The proposed system uses array partition mode and time division mode to achieve multi-target WPT. A novel quasi-Yagi antenna with enhanced gain is designed, consisting of a pair of dipoles, three directors, and a single split-ring resonator (SSRR), which is then used to form a 1×8 array for power transmission. The antenna has a bandwidth of 0.35 GHz with a frequency range of 2.25-2.6 GHz and a gain of 9.38 dBi. The total gain of the 1×8 array antenna is 17.23 dBi. An 8-way power divider is designed and implemented to feed the power amplifier (PA) of each array element, with isolation greater than 20 dB and return loss less than −17 dB. A digital phase and attenuation control circuit is also designed to achieve beam control. Measurement results show that at a distance of 3 meters, the maximum received power for single-target and multi-target schemes is 7.5 dBm and −2.6 dBm at each node, respectively. The system’s flexible beam control mode and high gain transmission characteristics can be used in scenarios such as wirelessly powering Internet of Things (IoT) multi-sensor networks.
Dual-band Circularly-polarized Millimeter-wave Substrate Integrated Waveguide Slot Antenna Array with a Small Frequency Ratio
Authors: Li Jianxing , Yu Xiaoyan , Wu Sifan , Yan Sen , Xu Kai-Da
Published: January 2025

In this paper, a 4×4 dual-band circularly-polarized (CP) substrate integrated waveguide (SIW) slot antenna array with a small frequency ratio (FR) is investigated in the Ka-band. The proposed antenna array achieves the small FR by radiating two high-order modes, i.e. TM130 and TM230, with close resonant frequencies. To realize CP performance, a sequential rotated feeding (SRF) network is used to design a 2×2 subarray. A 4×4 CP antenna array is further developed to enhance the directivity. Measured results show the antenna array achieves impedance bandwidth (|S11| < -10 dB) of 27.35-27.96 GHz at the lower band and 29.62-30.58 GHz at the higher band with an FR of only 1.1. The measured 3-dB axial-ratio (AR) bandwidths are obtained as 27.66-27.78 GHz and 30.34-30.45 GHz with right-handed circularly-polarized (RHCP) peak gains of 16.9 and 16.8 dBi, respectively. The proposed antenna array is a potential candidate for millimeter-wave communication systems.

Published: January 2025

In this paper, a broadband wide-angle leaky-wave antenna (LWA) with low sidelobe levels (SLL) is proposed. The antenna is composed of two parts: a broadband wide-angle scanning spoof surface plasmon polariton (SSPP)-fed circular patch antenna array and electromagnetic bandgap (EBG) structures tiled on both sides of the antenna array. By controlling the coupling distances between the circular radiation patches and SSPP feeding line, the attenuation constant along the radiation aperture is specially designed in a tapered way to achieve low SLL. EBG structures are adopted to reduce the back-lobe levels. Measured results show that the scanning angle of the proposed antenna reaches 82∘. The measured realized gains are from 8 to 15.7 dBi in the operating frequency range from 8 to 12 GHz, with a maximum SLL less than -15 dB. The wide-band wide-angle SSPP-fed LWA with low SLL can find applications in radar detection and microwave imaging.

Published: January 2025

The fifth generation (5G) communication, which is capable of realizing wireless communication with a extremely low latency and high data rate, has been put into commercial use widely. The propagation channel is of great significance for design, performance evaluation, and improvement of 5G system. As to investigate the wireless channel of 5G network, a channel measurement system based on passive sounding method is proposed in this paper. By utilizing the 5G downlink signal, e.g., synchronization signal block (SSB) and channel state information reference signal (CSI-RS), the proposed system is able to extract the multipath parameters of 5G propagation environment. Moreover, a measurement campaign is conducted at an urban macro-cellular (uMa) environment with the passive sounding system. The measured results is briefly analysed and compared with the 3rd generation partnership project (3GPP) results.

Abstract. Arshad A, Aditama R, Rahayu MS, Natawijaya A, Matra DD, Sudarsono S. 2024. Comparative study of chloroplast genomes across seven Salacca species. Biodiversitas 25: 4043-4058. Chloroplast (Cp) genomes play a vital role in comprehending plant evolution, biodiversity, and phylogenetics. Snake fruit is a tropical fruit in the Indo-Malayan region. This work compares seven Salacca species Cp genomes to clarify their genetics and evolutionary connections. Cp genomes were constructed using sequencing data from the BGISeq-500 platform and the GetOrganelle assemblers. The assembled Cp genomes have a standard four-part structure and vary in length from 157,047 to 158,182 kilobase pairs (kbp). Comparative genomics analysis found the ycf1 gene to have the highest number of single nucleotide polymorphisms (SNPs), revealing missing amino acids in Salacca affinis. The Cp genomes showed a high prevalence of mononucleotide SSR motifs. With a few exceptions, especially Salacca wallichiana, most Cp genomes showed stable borders between the large single copy (LSC), inverted repeat (IR), and short single copy (SSC) sections. This research underscores the importance of Cp genome information for identifying species, a crucial tool for evolutionary studies and breeding purposes. Furthermore, it emphasizes the intimate genetic connection between Salacca and Cocos nucifera, which contrasts with Phoenix dactylifera. This thorough research provides vital insights into the genetics of Salacca species and highlights the usefulness of Cp genome data in subsequent analyses.

Abstract. Marod D, Sungkaew S, Thinkampaeng S, Wachrinrat C, Hermhuk S, Thongsawi J, Phumphuang W, Yarnvudhi A, Yatar C, Cheysawat S, Sawasmongkol C. 2024. Natural tree regeneration after selective cutting in a dry evergreen forest in Northeastern Thailand. Biodiversitas 25: 4074-4085. Forest degradation is a serious problem caused by anthropogenic disturbance, nevertheless, forest recovery rates vary among forest ecosystems. We investigated forest regeneration after selective cutting in a dry evergreen forest at the Wang Nam Khiao Forestry Research and Training Station (WFRS), Nakhon Ratchasima Province, Thailand. In 2002, a 1-ha permanent plot was established in the forest. All woody plant (sapling and trees) in the plot with Diameter at Breast Height (DBH) >2 cm were identified, and their DBHs and positions were recorded. Data on environmental and topographic factors and soil properties were collected to analyze their relationships with tree spatial distribution. Tree monitoring was conducted in 2004, 2018, and 2020 and forest dynamics were analyzed for the periods 2002-2004, 2004-2018, and 2018-2020. In 2020, we identified 3,669 trees of 91 species, 81 genera, and 36 families. Based on importance index values, the dominant tree species (all with DBH ?4.5 cm) were Walsura pinnata Hassk., Dialium cochinchinense Pierre, Hopea ferrea Laness., Hydnocarpus ilicifolius King and Vitex scabra Wall. ex Schauer. Based on the DBH class distribution, the natural regeneration of all woody plants tended toward a reverse J-shaped, indicating a good regeneration condition. The results of forest dynamics analysis showed that the net recruitment rate (2.75±1.70% year-1) was higher than the mortality rate (2.14±0.73% year-1) throughout the study period. Tree spatial distributions varied among species and across environmental factors which were strongly influenced by soil texture followed by topographic and can be divided into generalist and specialist species. This indicates that the forest is going toward a positive regeneration trajectory after the disturbances. Nonetheless, additional information based on forest monitoring is required. Additionally, an understanding of the relationships between species niches and environmental changes is important for tree regeneration research and forest restoration programs; it will allow better matching of tree species to their optimal environmental conditions, thereby increasing the likelihood of plant community success.
Vulnerable agents: what we can learn from a child-centred perspective on transnational families
Authors: Bühler-Niederberger Doris
Published: January 2025

Research on children in transnational families benefits from a conceptual input as provided by the studies presented in this special issue. The input aims to overcome the usual juxtaposition of agency and vulnerability dominating the research field, a juxtaposition resulting from disciplinary preconceptions and not from empirical insights. In contrast, the results of the studies in this special issue clearly show that both agency and vulnerability exist, and in such a way that vulnerability may even be the result of the children’s actions. Therefore, a pragmatic theory of vulnerability is developed, based on the relational action concept of Emirbayer and Mische (1998). This theory understands vulnerability both as an accompanying phenomenon and as a consequence of agency, and links various forms of agency with the associated risks of vulnerability. Such an approach may be useful in research on children in various family constellations.
Flipping the Hierarchical Script: Black, Female Group Leaders Running Racially Diverse Groups
Authors: Henderson Fanita
Published: January 2025

Abstract: Black women leading racially diverse process groups encounter distinct hurdles as they navigate challenges related to hierarchical power dynamics and the complexities of overlapping identities. When group leaders adhere to expectations and pressures from members—where People of Color may hold significantly different expectations than White members—the risk of perpetuating White supremacy occurs. The article delves into the challenges Black women experience running racially diverse process groups and how I use mindfulness to help overcome many of those challenges.
