Multichannel Healthcare: Impact of Asynchronous Telemedicine Adoption on Patient Flow
Authors: Tushe Sokol , KC Diwas Singh , Ding Hao , Yeung Howa 
Published: October 2024

Problem definition: This paper studies a multichannel healthcare system where physicians diagnose patients and prescribe treatment in-person or through asynchronous telemedicine (AT), a widely adopted yet relatively under-explored form of telemedicine. In collaboration with physicians at the Veterans Healthcare Administration (VHA), we examine the impact of introducing an AT channel on the existing in-person channel and on overall system performance. Methodology/results: VHA implemented AT at select clinics in the state of Georgia in 2012. Using a difference-in-differences design, we find that the introduction of the AT channel led to a sorting process whereby more complex patients were seen in the in-person channel. AT implementation led to a 20% increase in recommended visit time and an 8.5% increase in required clinical resources for in-person consultations. In addition, the adoption of AT resulted in higher throughput—more patients seen by the specialists per month across both channels. Using a fixed-effects model we find a reduction in average wait time for in-person referrals (37.5%), and for the most common medically necessary procedure (43%) despite an increase in the total number of consultations at the specialist clinic. We attribute the improved efficiency to early patient triage, better match between patient needs and treatment modality, and reduction of setup and switching costs in physicians’ workflow. Managerial implications: This paper contributes to our understanding of a rapidly expanding form of healthcare delivery: multichannel healthcare with in-person and AT channels. Our results suggest that healthcare managers and physicians can adopt AT to improve overall system efficiency. At the same time, they should take into account the additional impact of AT on the in-person channel when making capacity decisions and developing guidance on patient referrals.

Discrimination Model Construction for Non-Lactational Mastitis and Breast Cancer Based on Imaging Features
Authors: Peng Jinjuan , Zhao Meng , Wang Shui 
Published: October 2024

Aims/Background The clinical presentation of non-lactational mastitis (NLM) shares similarities with some symptoms and examination results of breast cancer (BC), which can lead to misdiagnosis or delayed treatment. Current studies on breast lesions mostly focus on the diagnostic performance of a single imaging technique. This study aims to construct a discrimination diagnostic model for NLM and BC based on such imaging features as ultrasound and magnetic resonance imaging (MRI) and to validate the application value of the model, assisting clinicians in improving disease diagnosis and refining medical decisions. Methods This study is a retrospective analysis. Clinical data of 108 patients suspected of NLM based on imaging diagnosis, admitted to The First Affiliated Hospital with Nanjing Medical University between May 2018 and August 2023, were collected. Among them, 94 cases were pathologically confirmed as NLM and 14 cases as BC. Univariate and multivariate logistic regression analyses were performed on the patients’ clinical data, ultrasound features, and MRI features to select the risk factors for discriminating NLM and BC, and construct a discrimination model. The discrimination performance of the model was analyzed with the receiver operating characteristic (ROC) curve, decision curve analysis (DCA), and calibration curve. Results In the NLM group, there were 24 cases of granulomatous lobular mastitis (25.53%) and 70 cases of plasma cell mastitis (74.47%). In the BC group, there were 2 cases of infiltrating ductal carcinoma, 2 cases of atypical hyperplasia, 3 cases of papillary carcinoma, and 7 cases of ductal carcinoma in situ. Age, internal blood flow, calcification, edge, enhancement characteristics, apparent diffusion coefficient (ADC) values, and time-intensity curve (TIC) type were independent factors for differentiating NLM and BC (p < 0.05). The ROC analysis showed that the area under the curve of the model for discriminating NLM and BC was 0.920. The DCA results showed that the model had high net benefits for discriminating NLM and BC. The calibration curve analysis showed that the model had good consistency with the actual diagnosis of NLM and BC, with a chi-square value of 4.545 and a p-value of 0.155 according to the Hosmer–Lemeshow test. Conclusion Age, internal blood flow, calcification, edge, enhancement characteristics, ADC, and TIC curve types are important factors in distinguishing NLM and BC, and the model based on the above characteristics to distinguish NLM and BC has a high net benefit in distinguishing the two.
Calibrating a Heat Transfer Model for Baled Switchgrass Using Heat Generation
Authors: Schiavone Drew F. , Montross Michael 
Published: October 2024

HighlightsHeat and mass transfer in baled switchgrass was modeled based on thermal conductivity and internal heat generation.Model calibration was performed through a 60-day storage evaluation of baled switchgrass in an environmental chamber.Empirical models of heat generation and DML were developed based on thermal conductivity and aerobic respiration.Model validation was performed based on an energy balance and the aerobic respiration rate of switchgrass.Abstract. This study characterizes heat transfer within baled switchgrass through the development of a two-dimensional heat conduction model and an exponential drying approach to predict moisture content. The model was simulated using the finite difference method while accounting for the effect of internal heat generation to improve prediction accuracy. Model calibration was performed using rectangular bales of switchgrass (102 x 46 x 36 cm) stored in a controlled environmental chamber for 60 days at a fixed temperature and relative humidity. The heat and mass transfer model was implemented as an inverse model to empirically estimate heat generation and dry matter loss (DML). Internal heat generation and dry matter losses were also assessed using previously published models describing the aerobic respiration rate of switchgrass. Both heat generation models were in close agreement at a nominal moisture content of 10% w.b. (R2 = 0.9542) but deviated at nominal moisture contents of 20% to 40% w.b. (R2 &lt; 0.7543). DML simulated using the numerical model closely agreed with the DML measured in the storage evaluation (R2 &gt; 0.9060), indicating sufficient DML estimates through the conduction model and exponential drying approach. DML simulated through the published aerobic respiration model deviated to a greater extent, particularly at the highest moisture treatment (R2 = 0.4340), indicating an insufficient consideration of the various biochemical processes occurring at elevated levels of moisture and density. The results of this study provide a framework for the development of post-harvest quality models to optimize the storage, drying, and bioconversion of baled biomass feedstocks. Keywords: Bales, Heat and mass transfer, Heat transfer model, Storage losses, Switchgrass.

Published: October 2024

This paper presents an innovative active terahertz (THz) modulator that utilizes dynamic graphene-silicon arrays (DGSAs) to overcome the challenges of dynamically manipulating THz waves. The DGSA combines the exceptional electrical properties of graphene with the enhanced optical absorption capabilities of silicon arrays, enabling dual-mode active control through optical pumping and electrical biasing. An 808 nm laser is used to photoexcite carriers in the silicon arrays for optical pumping while a bias voltage modulates the Fermi level of graphene, subsequently varying Si conductivity and influencing the transmission properties of THz waves. Simulations have demonstrated modulation depths of up to 94% at 2.5 THz in the transmission mode and 89% at 1 THz in the reflection mode. Furthermore, this study delves into a theoretical analysis and numerical simulations, exploring the modulation mechanisms, including the role of graphene’s Drude model and PN junction effects. These insights provide a robust theoretical framework for understanding the DGSA’s operation and lay a solid foundation for the design and optimization of high-performance THz modulation devices.

Published: October 2024

A new, to our knowledge, simultaneous bi-directional all-optical multipoint-to-multipoint switching scheme is proposed and experimentally demonstrated for free-space optical (FSO) communication networks. Through tuning the optical switch at the core node, the communication link between each two arbitrary remote nodes can be established. The multipoint transmission performance is tested in a turbulence-tunable atmospheric cell using a 6.25 Gbit/s quadrature phase-shift keying (QPSK) signal. At the bit error rate (BER) of 1×10−3, the power penalty is <3.5dB with a 250°C temperature difference of the atmospheric cell. Moreover, this scheme is compatible with all-optical wavelength conversion, which can achieve strict transparency for different modulation formats. Our proposed scheme offers the possibility to provide an efficient, low-cost, and high-speed method for simultaneous bi-directional all-optical multipoint-to-multipoint FSO communications.
Heterogeneous nuclear ribonucleoprotein K is a potential target for enhancing the chemosensitivity of nasopharyngeal carcinoma
Authors: Yang Ming , Ke Zhaoyang , Wang Daji 
Published: October 2024

Abstract
The resistance of tumor cells to chemotherapy drugs is a critical determinant in the recurrence and metastasis of nasopharyngeal carcinoma (NPC). Therefore, it is crucial to identify effective biotargets that can enhance the sensitivity of NPC cells to chemotherapy drugs. Heterogeneous nuclear ribonucleoprotein K (hnRNPK) plays a central role in regulating chemotherapy resistance across various tumor types. However, its specific function in NPC cells remains unclear. This study reveals that hnRNPK is overexpressed in NPC tissues while weakly expressed in normal nasopharyngeal tissues. The expression level of hnRNPK is negatively associated with NPC patient survival. Importantly, hnRNPK is a key inducer of chemotherapy resistance in NPC, as evidenced by the significant increase in NPC cell sensitivity to cisplatin following hnRNPK knockdown. Mechanistically, hnRNPK induces chemotherapy resistance in NPC cells by suppressing the activation of the Akt/caspase 3 pathway. In NPC tumor-bearing mice, hnRNPK knockdown enhances the efficacy of cisplatin chemotherapy. Consequently, this work identifies a potential target for enhancing the sensitivity of NPC cells to chemotherapy.

Abstract
Dental implants provide functional and aesthetically pleasing dental replacements, but their longevity depends on biomechanical factors, physical characteristics, and patient variability. The present study used finite-element analysis to reveal the biomechanical response and potential modes of failure of dental implant systems subjected to normal occlusal loads. A generalized comparative assessment was carried out to measure the effect of the choice of crown material with zirconia, porcelain-fused-to-metal, and ceramic crowns. Such simulations showed complex patterns of stress distribution and deformation in the implant assembly with significant variation due to the mechanical properties of the crown material. Stiffer zirconia crowns magnified stress concentrations by 12.6, 10.8, 11.4, and 9.1% in the implant fixture, crown, cortical bone, and cancellous bone, respectively, compared with more compliant ceramic crowns. Furthermore, the maximal deformation of both the cortical and cancellous bone induced by zirconia crowns was higher by 21.1 and 19.2%, respectively, compared with the ceramic crowns. These results emphasize that the crown material properties are significant for controlling and modulation biomechanical load transfer, which plays a decisive role in the long-term durability and resistance to failure mechanisms such as interfacial debonding, bone resorption, and fatigue cracking. This study provides valuable information for optimizing implant designs and material selection that may improve clinical results, positively affecting patient satisfaction with dental implant therapy.
The role of biased polar question particles in discourse: the case of Macedonian zar and neli
Authors: Mitkovska Liljana , Bužarovska Eleni , Saračević Fevzudina 
Published: October 2024

Abstract
This paper focuses on biased polar questions in Macedonian headed by the interrogative particles zar and neli. These particles function as veridicality markers: neli asserts the truth of p, while zar challenges it by emphasizing the conflict between the epistemic and the evidential bias. Consequently, these questions have different discourse functions. Our goal is to examine the discourse-pragmatic properties of these questions and determine the factors influencing their distribution. We argue that their felicity depends on the interplay of contextual factors: the degree of speaker’s certainty in the truth of the proposition, the existence of conflicting contextual evidence, and the assertiveness component of the biased question. A statistical analysis of 340 examples from literary and social media sources revealed that the most decisive factor for the occurrence of neli- and zar-questions is the degree of speaker certainty in prior belief, highlighting the assertive force of neli-questions compared to the more inquisitive nature of zar-questions.
The Role of Math and Language Performance in Explaining the Gender Gap in STEM Major Choice. A Test for Germany
Authors: Uunk Wilfred 
Published: October 2024

Abstract
Across the globe, women choose science, technology, engineering, and mathematics majors (STEM) less often than men. One frequently suggested explanation of this gender gap is that women perform less well in math and better in language than men in secondary school and have a comparative advantage in language. Studies for the Anglo-Saxon context have only found weak support for this school performance explanation due to small gender differences in math performance and comparative (math-to-language) grade advantages and weak effects of comparative test advantages on STEM major choice. We aim to contribute to the literature by assessing the role of math and language competencies and grades in explaining the gender gap in STEM major choice for Germany, a country with considerable gender differences in math and language performance. Decomposition analyses of the gender gap in STEM major choice in higher tertiary education among upper secondary students from the German National Educational Panel Study show that math and language performance can explain nearly half of the gender gap in STEM major choice. The role of math competencies and grades in the German language proves especially important due to substantial gender differences herein and strong effects on the likelihood of STEM declaration. Our findings suggest that in contexts with strong gender differences in math and language performance, prior school performance can to a large extent explain women’s underrepresentation in STEM university majors.

Published: October 2024

Background: By 2030, the number of people with diabetes is estimated to increase to 366 million. As the number of people with diabetes increases, the development of microvascular complications also rises. DR is responsible for 4.8% of the 37 million cases of blindness worldwide. The present population-based study was carried out to estimate the prevalence of microalbuminuria in type 2 diabetes mellitus. This study aimed to investigate the relationship between microalbuminuria and the presence and severity of diabetic retinopathy in individuals with diabetes.
Methods: Patients with diabetic retinopathy who underwent urine albumin excretion testing in the retina clinic in 2022 were taken. The sample collected was a total of 200 patients with diabetic retinopathy. Each patient's clinical findings, OCT, and spot urine albumin were noted. Reports of other risk factors were collected. All parameters were compared between two groups (with and without nephropathy).
Results: The prevalence of microalbuminuria in patients with diabetic retinopathy and maculopathy is higher. Patients with microalbuminuria mostly had severe NPDR and PDR.
Conclusions: Patients with microalbuminuria would have more severe retinopathy compared to those without nephropathy. This study helps ophthalmologists in the early detection of the risk of developing diabetic retinopathy and prevents its progression by careful monitoring.

Authors: Kobojek Elżbieta 
Published: October 2024

Ważnym elementem rzeźby nizinnej części Polski są wydmy śródlądowe. Cechy wyróżniające ekosystem wydmowy, do których należą: wybitna jednorodność materiału (piaski drobnoziarniste i średnioziarniste), skład mineralny zdominowany przez kwarc, przepuszczalność i suchość podłoża, bardzo słabe gleby, ubóstwo składników pokarmowych dla roślin, mają duży wpływ na sposób jego użytkowania. Obecnie w środkowej Polsce wydmy są głównie zalesione. W obrębie gminy Uniejów najwięcej wydm śródlądowych występuje w dolinie Warty. W artykule przedstawiono rozmieszczenie i genezę wydm, cechy ekosystemu, formy współczesnego użytkowania oraz jego zmiany w ciągu ostatnich stu lat. Szczególną uwagę zwrócono na rolę wydm w lokalizacji zabudowy wiejskiej w dolinie Warty. Suche, piaszczyste obszary wydmowe pozostające poza zasięgiem wód powodziowych wielokorytowego systemu Warty bardziej sprzyjały zabudowie niż okresowo zalewane fragmenty dna doliny. Zasięg zabudowy wiejskiej, zwartej i rozproszonej, prawie nie uległ zmianie w ciągu ostatnich stu lat.
