Non-Markovian Pitch-angle Scattering as the Origin of Particle Superdiffusion Parallel to the Magnetic Field
Authors: Zimbardo Gaetano , Perri Silvia 
Published: November 2020

Abstract
We develop a theoretical model for particle superdiffusive transport parallel to the average magnetic field, due to the pitch-angle scattering times having a non-Markovian, power-law probability distribution. We show that a non-Markovian Fokker–Planck equation can be derived, where the traditional time derivative is changed for a fractional time derivative. By solving the fractional Fokker–Planck equation, with the time-dependent part having solutions that are expressed by the Mittag-Leffler functions, it is found that an initial pitch-angle distribution slowly decays toward isotropy. This leads to a parallel velocity autocorrelation function that also has a slow power-law decay in time, thus implying superdiffusive transport in the direction parallel to the background magnetic field. In this framework, we derive for the first time the anomalous diffusion coefficient as a function of physical parameters like the background magnetic field, the resonant turbulence level, and the particle speed.

Abstract
The Parker Solar Probe (PSP) and Solar Orbiter missions are designed to make groundbreaking observations of the Sun and interplanetary space within this decade. We show that a particularly interesting in situ observation of an interplanetary coronal mass ejection (ICME) by PSP may arise during close solar flybys (<0.1 au). During these times, the same magnetic flux rope inside an ICME could be observed in situ by PSP twice, by impacting its frontal part as well as its leg. Investigating the odds of this situation, we forecast the ICME rate in solar cycle 25 based on two models for the sunspot number (SSN): (1) the forecast of an expert panel in 2019 (maximum SSN = 115), and (2) a prediction by McIntosh et al. (2020, maximum SSN = 232). We link the SSN to the observed ICME rates in solar cycles 23 and 24 with the Richardson and Cane list and our own ICME catalog, and calculate that between one and seven ICMEs will be observed by PSP at heliocentric distances <0.1 au until 2025, including 1σ uncertainties. We then model the potential flux rope signatures of such a double-crossing event with the semiempirical 3DCORE flux rope model, showing a telltale elevation of the radial magnetic field component B

Universal at Last? The Splashback Mass Function of Dark Matter Halos
Authors: Diemer Benedikt 
Published: November 2020

Abstract
The mass function of dark matter halos is one of the most fundamental statistics in structure formation. Many theoretical models (such as Press–Schechter theory) are based on the notion that it could be universal, meaning independent of redshift and cosmology, when expressed in the appropriate variables. However, simulations exhibit persistent nonuniversalities in the mass functions of the virial mass and other commonly used spherical overdensity definitions. We systematically study the universality of mass functions over a wide range of mass definitions, for the first time including the recently proposed splashback mass,

. We confirm that, in ΛCDM cosmologies, all mass definitions exhibit varying levels of nonuniversality that increase with peak height and reach between 20% and 500% at the highest masses we can test.

,

, and

exhibit similar levels of nonuniversality. There are, however, two regimes where the splashback mass functions are significantly more universal. First, they are universal to 10% at

, whereas spherical overdensity definitions experience an evolution due to dark energy. Second, when additionally considering self-similar cosmologies with extreme power spectra, splashback mass functions are remarkably universal (to between 40% and 60%), whereas their spherical overdensity counterparts reach nonuniversalities between 180% and 450%. These results strongly support the notion that the splashback radius is a physically motivated definition of the halo boundary. We present a simple and universal fitting formula for splashback mass functions that accurately reproduces our simulation data.

Authors: Wijanarko Dionisius Panji , Djajakusumah Teguh Marfen , Hapsari Putie , Nusjirwan Rama 
Published: November 2020

Latar Belakang. Penyakit ginjal kronis merupakan masalah kesehatan masyarakat global dengan prevalensi dan insidensi Gagal Ginjal Terminal (GGT) yang meningkat. Riset Kesehatan Dasar Indonesia menyatakan perawatan penyakit ginjal menjadi beban kedua tertinggi pembiayaan BPJS. Penganti fungsi ginjal yang umum dilakukan adalah hemodialisis (HD) sehingga akses vaskular menjadi hal penting dalam penanganan GGT. Fistula arteriovena (AVF) radiosefalika merupakan pilihan akses HD yang utama. Respon endotel merupakan aspek penting dari remodeling pembuluh darah yang diperlukan untuk keberhasilan AVF. C-Reactive Protein (CRP) yang bersirkulasi tinggi dapat menyebabkan disfungsi endotel sehingga diduga memiliki nilai prediksi terhadap maturasi AVF.
Metode. Desain analitik menggunakan metode kohort prospektif dengan consecutive sampling untuk menilai bagaimana pengaruh kadar CRP serum preoperatif terhadap maturasi AVF. Sampel diambil dari pasien GGT yang datang ke poliklinik Bedah RSUP Hasan Sadikin dan RSKG Ny.R.A.Habibie Bandung yang akan menjalani operasi AVF radiosefalika. Tes statistik menggunakan uji univariat untuk dekskripsi data. Perbedaan kadar CRP serum preoperatif berdasarkan perbedaan status maturasi AVF dianalisis melalui perbandingan kadar CRP serum preoperatif antar kelompok maturasi AVF melalui model bivariat uji t independen. Selanjutnya analisis untuk menguji hipotesis melalui analisis regresi logistik dengan batas kemaknaan 0,05.
Hasil. Didapatkan 24 pasien (12 laki-laki, 12 perempuan) yang dilakukan analisis dengan rerata usia 45 (±16) tahun, rerata tekanan sistolik 149,2 (±28,4)mmHg. Didapatkan kadar CRP serum preoperatif berpengaruh negatif secara signifikan terhadap maturasi AVF dengan
probabilitas kesalahan statistik sebesar p = 0,0285 (<0,05) dengan koefisien determinasi Nagelkerke (Nagelkerke R Squared) sebesar 71,1%. Derajat kuatnya pengaruh kadar CRP serum preoperatif terhadap maturasi AVF tergolong kuat/tinggi berdasarkan klasifikasi Guilford yaitu 0,843 (0,70 – 0,90).
Kesimpulan. Terdapat pengaruh kadar CRP serum preoperatif terhadap maturasi fistula radiosefalika. Semakin tinggi kadar CRP serum preoperatif, semakin rendah probabilitas maturasi fistula radiosefalika.

The Timed Up-&-Go Test: Preliminary Age- and Sex-related Reference Values for Older Filipino Adults
Authors: Gorgon Edward James R. 
Published: November 2020

Objective. The Timed Up-&-Go Test (TUGT) is a clinically useful measure that has been widely used in practice toassess functional mobility in older people. Interpretation of TUGT scores relies on appropriate reference values.This study aimed to describe preliminary age- and sex-related reference values for the TUGT for Filipinos aged60–79 years.
Methods. This is a descriptive cross-sectional study. We included Filipino adults aged 60–79 years, with no significantdisability, and resided in metropolitan areas in the National Capital Region and rural communities in southernLuzon. All participants completed the TUGT. Data were analyzed descriptively and reported as means, standarddeviations, and 95% confidence intervals.
Results. A total of 156 community-dwelling older adults participated in the study with mean age (SD) of 68 (5)years. The majority were women (103/156, 66%). Mean (SD) TUGT score for all participants was 11.0 (2.4) seconds.Overall, men completed the test faster compared to women, and individuals in the 60–69 years age group hadshorter completion times than those in the 70–79 years age group.
Conclusion. In the absence of definitive reference values for older Filipino adults, this study provides preliminaryguidance for interpreting TUGT performance for the purposes of screening and monitoring functional mobilityimpairments in this population.

Authors: Paterno Elizabeth R. 
Published: November 2020

Objectives. This study aims to (1) determine the cardiovascular risk of persons with hypertension and diabetesattending hypertension/diabetic clinics or hypertension/health club meetings in the AMIGA (Alfonso, Mendez,Indang, General Emilio Aguinaldo and Amadeo) municipalities of Cavite; (2) suggest measures to improve thecardiovascular disease (CVD) program in these municipalities using the results of the study.
Methods. A cross-sectional study was performed on patients diagnosed with hypertension and/or diabetes whoare attending clinics or club meetings in the barangays of the five AMIGA municipalities of Cavite. Participantswere interviewed using an abbreviated version of the World Health Organization (WHO) STEPS questionnaireon risk factors. The participants’ anthropometric measurements were obtained and their total blood cholesterollevels determined. CVD risk was then estimated using the WHO / International Society of Hypertension (ISH) riskprediction chart for the Western Pacific Region B.
Results. 1,032 participants from 27 barangays qualified for the study. Participants were predominantly female(74%); over-all mean age was 58.43 years. Majority of the participants (79.17%) were found to be in the low-riskgroup; 11.34% were in the moderate risk group; 4.46% were in the high-risk group; while 5.05% were in the veryhigh-risk group. Majority of the participants were also found to be obese. Mean total cholesterol was 207.02 mg/dl.
Conclusion. Majority of participants were stratified in the low-risk category (<10% chance to have cardiovascularevents in the next 10 years), while 9.5% were in the high-risk category (≥20% risk). Obesity is a major risk factorthat could be addressed in this population.

Authors: Redondo Marie Jeazelle H. , Santiago Alvina Pauline D. , Dualan Ivo John S. 
Published: November 2020

Objectives. Refractive changes have been studied after muscle surgery in literature but most results are inconsistent.It has been postulated that changes in corneal tension after muscle surgery may cause a change in corneal curvatureresulting in the change in refraction postoperatively. This study investigated changes in corneal topography andclinical refraction after horizontal rectus muscle surgery.
Methods. Twenty-one eyes of 13 patients underwent horizontal rectus muscle surgery via limbal approach. Manifestrefraction, cycloplegic refraction, and corneal topography were measured preoperatively, and postoperatively at day 1and weeks 1, 2, 4 and 8. The proportion of subjects with at least 0.5 D change from preoperative measurements and the proportion of subjects that needed new prescription postoperative were also computed. Analysis of the results were done using the Friedman test to identify significant differences among measurements at different time periods with post-hoc analysis utilized to identify specific time periods with significant changes from preoperative measurements.
Results. Mean corneal keratometry, horizontal, vertical, and oblique astigmatism, obtained topographically showed nosignificant difference from preoperative measurements. The statistically significant difference in corneal astigmatismin the recession group at day 1, week 4 and week 8 postoperatively was not confirmed when converted to powervectors in both vertical/horizontal (J0) and oblique (J45) astigmatism. Clinical refraction showed a transient myopicshift in spherical equivalent, statistically significant only on postoperative day 1 in the recession group. There was nostatistically significant difference in clinical astigmatism. There was ≥ 0.5 D change in spherical equivalent in 60% inboth study groups by the end of follow-up. The shift in J0 was more than 10% in the recession group. More than fiftypercent (52.4%) needed new prescription for glasses.
Conclusion. No statistically significant change in corneal topography and clinical refraction following horizontal rectusmuscle surgery were found. Patients should still be refracted at least 2 weeks postoperatively to check if there is aneed for change in prescription glasses to improve alignment and/or improve vision.

Authors: B. Rivera Ana Kriselda , Bullecer Ernani R. , Latorre Angelica Anne E. 
Published: November 2020

Background. Anemia is the most common medical disorder throughout a woman’s life. Given that anemia during reproductive years impacts future gestational and perinatal health, then any factors possibly associated with the disorder should be studied and ultimately addressed.
Objective. This study aimed to determine anemia prevalence and its associated factors (socio-demographic,lifestyle, knowledge, dietary and biochemical) among a select group of women of reproductive age (WRA) living in Tondo, Manila.
Methods. This is an analytic cross-sectional study that utilized interviewer-assisted questionnaire and bloodextraction to collect data from 166 WRA (18-40 years).
Results. Anemia prevalence among the study participants was found to be 9.0%. In terms of associated factors,being anemic was found to be more likely if the WRA has these factors: higher parity, graduated from college;unemployed; living in a low-income household; took iron supplements, and; have low knowledge on iron. On the other hand, increase in age, increase intake of heme iron and non-heme iron food sources, and an increase in blood ferritin concentration were factors that made anemia less likely among WRA.
Conclusion. Examining these factors provides insight into the multicausal nature of anemia. Thus, preventionand control programs should focus on the contribution and interrelatedness of these factors to address anemia.
Hispanic Racialization, Citizenship, and the Colorado Border Blockade of 1936
Authors: Varsanyi Monica W. 
Published: November 2020

Abstract
In April of 1936, Governor Edwin “Big Ed” Johnson of Colorado declared martial law in a one-mile strip along the state’s southern border with New Mexico, claiming that an invasion of “aliens and indigents” threatened the well-being of Colorado and its citizens. In addition to literally placing a militarized boundary between the more Anglo state of Colorado and the heavily Hispanic state of New Mexico, Johnson’s blockade also heightened contestations over the social boundary between who belonged and who fell outside of citizenship and belonging. Those crossing the New Mexico-Colorado border for work included Mexican immigrants as well as New Mexican Hispanics who were long-time US citizens, most of whom were racialized as undesirable foreigners by many Anglo residents. Interestingly, during the blockade, many native-born Hispanics in New Mexico and Colorado also characterized Mexican immigrants in a negative light, while simultaneously and vigorously asserting their belonging as Spanish American citizens of the United States. The scholarly literature on the racialization of Hispanics has generally approached Mexican-origin people as a unitary group, explored their racial identity in contrast to Anglos, and, less often, taken into account tensions over racialization as they played out between different Hispanic groups. In response, this article details how Johnson’s blockade contributed to the racialization—by both Anglos and Hispanics—of Mexican immigrants and Hispanics in the Southwest during the New Deal Era. This case study also offers a rare example of a state’s attempt to usurp the federal government’s plenary power over immigration during the twentieth century, a time when the federal government’s control over immigration was relatively unquestioned.
