Clinopodium haraverianum (Lamiaceae: Menthinae), una especie nueva de San Sebastián del Oeste, Jalisco, México
Authors: González-Gallegos Jesús Guadalupe , Figueroa Dante S. , Velázquez-Ríos Perla 
Published: February 2023

Antecedentes: La delimitación genérica y las relaciones filogenéticas de Clinopodium son aún inestables. En México se registran 15 especies que alguna vez fueron tratadas también bajo los géneros Calamintha o Satureja. Exploraciones recientes en el occidente de México condujeron al descubrimiento de una especie adicional con corolas relativamente largas y de tono rojizo, lo que corresponde al conjunto antes reconocido como Satureja sect. Gardoquia.
Preguntas: ¿cuáles son las características morfológicas diagnósticas que soportan a la especie nueva?, ¿cuáles son las especies morfológicamente similares?
Especies de estudio: especies de Clinopodium de México y de Satureja sect. Gardoquia.
Sitio y años de estudio: San Sebastián del Oeste, Jalisco, primavera de 2022.
Métodos: Recolección botánica, herborización y caracterización morfológica de los especímenes recolectados. Cotejo de literatura especializada, ejemplares de herbario y tipos nomenclaturales en línea.
Resultados: La especie nueva Clinopodium haraverianum se distingue del resto de especies del género por la combinación de los siguientes caracteres: hábito herbáceo no ramificado, hojas progresivamente reducidas hacia el ápice del tallo, cáliz marcadamente bilabiado, corolas con el tubo mayor de 16 mm de largo y de tono rojizo. La especie más parecida es C. macrostemum con la que se compara en la diagnosis.
Conclusiones: Clinopodium haraverianum se separa de la mayoría de las especies de Clinopodium al reunir las características que definen al grupo Gardoquia, y dentro de este destaca por su hábito y tamaño de las estructuras florales. Esta especie constituye una adición a la flora endémica de Jalisco y por extensión de México.

Authors: Belov Dmitrii F. , Nikolaenko Vadim P. 
Published: February 2023

Aim. To estimate the influence of concomitant glaucoma (including that after surgery) on IOL power calculation accuracy before phacoemulsification.
Materials and methods. 413 patients were included in the study divided in 4 groups: 1st patients with cataract and no concomitant glaucoma (251 cases); 2nd patients with cataract and primary open-angle glaucoma (POAG) on medical therapy (103 cases); 3rd patients with cataract and prior trabeculectomy (42 cases); 4th patients with cataract and primary angle-closure glaucoma (PACG) on medical therapy (17 cases). In all patients, the IOL power calculation was performed using optical biometry (IOL-Master 500). 1 month after surgery, desired refraction according to Barrett Universal II Formula and real obtained refraction estimated by automatic refractometry (Topcon-8800) were compared.
Results. There was no significant difference between study groups 13 in IOL power calculation accuracy (the calculation error was 0.09 0.39 D, 0.08 0.45 D, 0.03 0.49 D, for each group respectively). However, we found a higher myopic shift (0.47 0.48 D, p = 0.095) in the 4th group.
Conclusion. The presence of concomitant POAG on medical therapy, same as earlier trabeculectomy, does not demand any modification of the IOL calculation algorithm. However, in PACG patients we recommend taking 0.5 D lower optical power IOLs to avoid excessive myopic refraction after phacoemulsification.

Published: February 2023

Thousands of fans descend onto college campuses every Saturday during the fall to watch National Collegiate Athletic Association (NCAA) Division I Power 5 and Group of 5 college football games. Power 5 is used to describe five of ten athletic conferences (ACC, Big Ten, Big 12, Pac-12, and the SEC) which are considered the most prominent and highest earning athletic conferences in college football whose teams compete in the NCAA Division 1 Football Bowl Subdivision (FBS). Group of 5 is an assembly of five conferences that also compete in NCAA Division I FBS. Group of 5 college football teams often compete against Power 5 and Independent teams during the regular season and bowl games (Vannini, 2022). The largest stadium seating capacity Group of 5 schools is around 40,000 people compared to the Power 5 stadiums, 10 of which seat at least 90,000 people (Chiusano, 2022). While the seating capacity at Group of 5 schools is not as great as Power 5 institutions it still represents a significant population (Vannini, 2022).

Authors: Ananya Arnna , Pal Manidip , Bhadra Banasree , Sarkar Suvobrata 
Published: February 2023

Background: To analyse the effects of antenatal dexamethasone on fetal heart rate variability (fHRV), when administered to mothers between 30-37 weeks of gestation, at risk of preterm delivery and corroborate presenting maternal symptoms with mode of delivery and perinatal outcomes.
Method: Prospective observational study conducted for 1 Year among pregnant women with gestation between 30 completed weeks to 36 weeks 6 days, with symptoms suggesting risk of preterm delivery. The sample size calculated was 52. Dexamethasone phosphate, 24 mg in 4 divided doses, was administered as intramuscular injections 12 hours apart. NST tracings were taken at three points-before first dose, one hour after first dose and one hour after the fourth dose. Chi-square test and Paired t test was applied, p<0.05 was considered statistically significant.
Results: Strong correlation was found between antenatal dexamethasone administration and fHRV (p<0.05) which increased after administration of the first dose of dexamethasone compared to its value prior to administration. There was a further increase after the fourth dose.
Conclusions: Dexamethasone is associated with increase in fHRV evident on non-stress test recordings, without significant decrease in baseline fetal heart rate.

<p class="06IsiAbstrak">This study aims to explain the Islamic studies <span lang="EN-GB">curriculum</span> based on religious moderation in higher education institutions (HEIs). In developing an Islamic studies curriculum, it is necessary to have an integrated concept between goals, materials, strategies, and evaluation. Curriculum development also needs to pay attention to supervision and cooperation with the Ministry of Religion and partnerships with religious leaders. The focus of Islamic studies based on religious moderation in HEIs is the Islamic religious education course. This literature research used primary data from books on the HEIs curriculum and learning Islam in HEIs. Meanwhile, secondary data sources came from books and articles related to the Islamic studies curriculum in HEIs. The findings revealed that for the measurable construction of Islamic studies curriculum in HEIs, it should fulfill at least three aspects: (1) normative curriculum construction, (2) current facts curriculum construction, and (3) curriculum reconstruction (rearrangement). This research further contributes to HEIs in compiling Islamic studies curricula to create students with a moderate attitude.</p><p> </p>
Dynamic Analysis of a Downhole Regulator for Drilling in Interbedded Formations
Authors: Aribowo Arviandy G. , Wildemans Roeland , Detournay Emmanuel , van de Wouw Nathan 
Published: February 2023

Summary
In this paper, we investigate the effect of a downhole passive regulator [anti-stall tool (AST)] on the dynamics of rotary drilling systems in interbedded formations. Drilling in interbedded formations can significantly affect the vibrational signature of these systems and the associated drilling performance. Hence, models to assess the impact of drilling in such formations are needed. Here, we construct a dynamic model of the drillstring system which incorporates the bit/rock interface laws for the transitional phase of bit motion between rock layers with distinct mechanical properties. In the model, the axial and torsional dynamics of the drillstring systems are coupled by these interface laws and cast in the form of discontinuous (state-dependent) delay differential equations. Next, we include the AST in the dynamic model to enable the assessment of the influence of this downhole tool on drilling performance, in particular in terms of rate-of-penetration (ROP) and drilling efficiency. Furthermore, we also investigate the mechanical specific energy (MSE) and steady-state power losses at the bit (due to frictional torque) for different operational conditions and rock layer thicknesses. The analysis reveals that an increased drilling efficiency and lower MSE are obtained by incorporating the downhole tool in the drillstring, resulting in a higher ROP and a lower frictional contact between the bit and rock in interbedded formations.
Transient Flow Performance of a Vertical Well With Multiple Varying Conductivity Fractures in a Tight Oil Reservoir

Published: February 2023

Summary
Due to uneven proppant distribution and varied proppant sizes during hydraulic fracturing, artificial fractures of varying length, asymmetry, and varying conductivity are easily formed near the wellbore. The principal focus of this work is to investigate the pressure transient performance of a vertical well penetrated by multiple asymmetrical fractures with varying lengths and varying conductivities in a tight oil reservoir. A novel fracture flow equation was developed specifically to describe the flow behavior inside the complex artificial fractures mentioned above. By combining with the point source solution of the tight oil reservoir, a semianalytical solution was further obtained to analyze the pressure transient behavior of a vertical well with multiple varying-conductivity fractures in a tight oil reservoir. The accuracy and reliability of the newly-developed solution were verified by comparing with the result of a numerical model. With this new solution, fracture flux distribution for different conductivity modes, namely, linearly declining mode, exponentially declining mode, and elliptically declining mode, shows that the near-wellbore fracture flux of the exponential mode is greater than that of the other two modes, but the flux distribution near the fracture tips is on the contrary. Meanwhile, the transient flow characteristics under the above varying conductivity modes indicate that the exponentially varying conductivity has a significant influence on the early linear flow regimes, while the linear and elliptical mode only has a slight influence on the bilinear flow regime under high conductivity. Parameter sensitivity analysis reveals that the obvious inversion point occurring in the pressure derivative curves of uniform conductivity fractures disappears on the pressure derivative curves of varying conductivity fractures, and a weaker asymmetry, a greater adjacent fracture angle, and a larger fracture number and fracture length ratio are conducive to improve the fracturing stimulation effect. This study deepens our understanding of the transient flow performance of vertically fractured wells and helps to estimate artificial fracture properties and evaluate hydraulic fracturing performance.

Abstract
Background: Permanent supportive housing (PSH) is an evidence-based practice to address homelessness. This paper describes the protocols for a mixed-methods comparative effectiveness study of two distinct approaches to implementing PSH and patient-centered quality of life, health care utilization, and health behaviors that reduce COVID-19 risk.
Methods: People experiencing homelessness who are placed in either (a) single-site (place-based) PSH or (b) scatter-site PSH completed 6 monthly surveys after move-in using smartphones provided by the study team. A subsample of participants completed three qualitative interviews at baseline, 3 months, and 6 months. Two stakeholder advisory groups, including one featuring people with lived experience of homelessness, helped guide study decisions and interpretations of findings.
Discussion: Recruitment during the pandemic was challenging given that in-person contact was not permitted at times either by the recruitment sites or research institutions during COVID-19 surges and high community transmission, which particularly affected homelessness programs. To overcome these challenges, flexible strategies were employed that included extending the recruitment period and distribution of cell phones with paid data plans.

Authors: Cao Xiaomeng , Kang Wendi , Xia Tianhong , Yuan Shaobin , Guo Changan , Wang Wenjie , Liu Hongbin 
Published: February 2023

Abstract
Objective: To explore the relationship between the circular clock gene NPAS2 (neural PAS domain protein 2) and the survival prognosis of gastric cancer (GC) patients and clarify its role in evaluating GC prognosis.
Methods: The tumor tissues and clinical data of 101 patients with GC were collected retrospectively. Immunohistochemical staining (IHC) was used to detect the expression of NPAS2 protein in GC and adjacent tissues. Univariate and multivariate Cox regression analysis was used to determine the independent prognostic factors of GC, and a nomogram prediction model was established. The ROC curve, the ROC area under the curve (AUC), the calibration curve, and C-index were used to evaluate the predictive effectiveness of the model. Kaplan Meier analysiswas used to compare the risk stratification of subgroups according to the median score in the nomogram model of each patient.
Results: Microarray IHC analysis showed that the positive rate of NPAS2 protein expression in GC tissues was 65.35%, which was significantly higher than 30.69% in adjacent tissues. The high expression of NPAS2 was correlated with TNM stage (P<0.05), pN stage (P<0.05), metastasis (P<0.05), venous invasion (P<0.05), lymphatic invasion (P<0.05), and lymph node positive (P<0.05) of GC. Kaplan Meier survival analysis showed that the 3-year overall survival (OS) of patients with high NPAS2 expression was significantly shortened (P<0.0001). Univariate and multivariate COX regression analysis showed that TNM stage (P=0.009), metastasis (P=0.009), and NPAS2 expression (P=0.020) were independent prognostic factors of OS in GC patients for 3 years. The nomogram prediction model based on independent prognostic factors has a C-Index of 0.740 (95% CI: 0.713-0.767). Furthermore, subgroup analysis showed that the 3-year OS time of the high-risk group was significantly lower than that of the low-risk group (P<0.0001).
Conclusion: NPAS2 is highly expressed in GC tissues and is closely related to worse OS in patients. Therefore, the evaluation of NPAS2 expression may be a potential marker for GC prognosis evaluation. Notably, the nomogram model based on NPAS2 can improve the accuracy of GC prognosis prediction and assist clinicians in postoperative patient management and decision-making.

Published: February 2023

Abstract
Understanding how individual memory traces are reactivated during sleep is instrumental to the theorizing of memory consolidation, a process during which newly acquired information becomes stabilized and long-lasting. Via targeted memory reactivation (TMR), a technique that unobtrusively delivers learning-related memory cues to sleeping participants, we examined the reactivation of individual memories during slow-wave sleep and how canonical neural oscillations support item-specific memory reactivation. Furthermore, we investigated how pre-sleep testing, which presumably induces fast consolidation before sleep, would modulate sleep-mediated memory reactivation. Applying multivariate representational similarity analysis (RSA) to the cue-elicited electroencephalogram (EEG), we identified significant item-specific representations in two post-cue time windows (620-1350 ms and 2270-3190 ms) for post-sleep remembered items, with only the later item-specific representations contributing to memory consolidation. Untested items (i.e., items that were not tested pre-sleep), but not tested items, elicited higher spindles that predicted stronger item-specific representations and post-sleep memories. Notably, for untested items, the strengths of memory reactivation and spindles were temporally coupled to the up-state of the slow oscillation activity. Together, our results unveiled how item-specific memory reactivation and its link with neural oscillations during sleep contributed to memory consolidation. This knowledge will benefit future research aiming to perturb specific memory episodes during sleep.

Abstract
In this paper,the method of solid phase extraction-inductively coupled plasma mass spectrometry was established for the determination of 12 kinds of heavy metal elements, including Alum(V), manganese(Mn), iron(Fe), cobalt(Co), nickel(Ni), copper(Cu), zinc(Zn), gallium(Ga), cadmium(Cd), tin(Sn), lead(Pb) and uranium(U) in high-salt foods. After the sample was digested by microwave and acid drived out, the pH value of digestion solution was adjusted with 1.0 mol/L ammonium acetate buffer solution.The interfering salts of Na and K were removed but the heavy metal elements were adsorbed on the extraction column filled with resin.Then the 12 kinds of heavy metal elements were eluted by 2 mol/L nitric acid and enter the ICP-MS for measurement. The method established in this study can reduce the interference of salt on the detection. It has accurate quantification and good repeatability and it is suitable for the determination of 12 kinds of heavy metal elements in high-salt foods.
Temperature-compensated calibration of cross-style hotwire anemometers
Authors: Finke Colton , White Edward B. 
Published: February 2023

Abstract
Velocity measurements collected using constant-temperature hotwire anemometers are sensitive to variation in the ambient temperature. This research defines a methodology for calibrating cross-style hotwires from which temperature-compensated estimates of the streamwise and spanwise components of velocity are obtained. Four calibration sweeps are conducted that account for the effects of ambient temperature, flow angularity, and velocity magnitude. A freestream calibration verification experiment establishes that the relative calibration error is less than 2% of the velocity components for flow angles up to ±20°. The corresponding flow-angle uncertainty is less than ±1.0°.

Abstract
Domain wall structures form spontaneously due to epitaxial misfit during thin film growth. Imaging the dynamics of domains and domain walls at ultrafast timescales can provide fundamental clues to features that impact electrical transport in electronic devices. Recently, deep learning-based methods showed promising phase retrieval (PR) performance, allowing intensity-only measurements to be transformed into snapshot real space images. While the Fourier imaging model involves complex-valued quantities, most existing deep learning-based methods solve the PR problem with real-valued-based models, where the connection between amplitude and phase is ignored. To this end, we involve complex numbers operation in the neural network to preserve the amplitude and phase connection. Therefore, we employ the complex-valued neural network for solving the PR problem and evaluate it on Bragg coherent diffraction data streams collected from an epitaxial La2-xSrxCuO4 (LSCO) thin film using an X-ray Free Electron Laser (XFEL). Our proposed complex-valued neural network-based approach outperforms the traditional real-valued neural network methods in both supervised and unsupervised learning manner. Phase domains are also observed from the LSCO thin film at an ultrafast timescale using the complex-valued neural network.
