Published: March 2021

Abstract
We investigate the photovoltaic behaviors of magnetic graphene interconnect junctions, which are constructed by zigzag graphene nanoribbons (ZGNRs), with the aim to produce pure spin current by photogalvanic effect (PGE). Two kinds of interconnect junctions are designed by connecting two 6-ZGNR with a carbon hexagon (C6) and a carbon tetragon (C4), respectively. It is found that zero charge current is produced under irradiation of light in both structures due to the presence of spatial inversion symmetry. Nevertheless, behind the zero charge current, net pure spin current is produced in the structure with a C6, but not in the structure with a C4. This difference originates from their different edge state distribution and different spatial inversion symmetry of the spin density. However, interestingly, local edge pure spin current can be obtained in both structures. More importantly, the pure spin current generation is independent of the photon energy, polarization type or polarization angle, suggesting a robust way of generating pure spin current with PGE and new possibility of graphene’s applications in spintronics.

Abstract
We study how nanophotonic structures can be used for determining the position of a nearby nanoscale object with subwavelength accuracy. Through perturbing the near-field environment of a metasurface transducer consisting of nano-apertures in a metallic film, the location of the nanoscale object is transduced into the transducer’s far-field optical response. By monitoring the scattering pattern of the nanophotonic near-field transducer and comparing it to measured reference data, we demonstrate the two-dimensional localization of the object accurate to 24 nm across an area of 2 × 2 μm. We find that adding complexity to the nanophotonic transducer allows localization over a larger area while maintaining resolution, as it enables encoding more information on the position of the object in the transducer’s far-field response.

Mutations in thePRPH2gene encoding the photoreceptor-specific protein PRPH2 (also known as peripherin-2 or rds) cause a broad range of autosomal dominant retinal diseases. Most of these mutations affect the structure of the light-sensitive photoreceptor outer segment, which is composed of a stack of flattened “disc” membranes surrounded by the plasma membrane. The outer segment is renewed on a daily basis in a process whereby new discs are added at the outer segment base and old discs are shed at the outer segment tip. New discs are formed as serial membrane evaginations, which eventually enclose through a complex process of membrane remodeling (completely in rods and partially in cones). As disc enclosure proceeds, PRPH2 localizes to the rims of enclosed discs where it forms oligomers which fortify the highly curved membrane structure of these rims. In this study, we analyzed the outer segment phenotypes of mice of both sexes bearing a single copy of either the C150S or the Y141C PRPH2 mutation known to prevent or increase the degree of PRPH2 oligomerization, respectively. Strikingly, both mutations increased the number of newly forming, not-yet-enclosed discs, indicating that the precision of disc enclosure is regulated by PRPH2 oligomerization. Without tightly controlled enclosure, discs occasionally over-elongate and form large membranous “whorls” instead of disc stacks. These data show that the defects in outer segment structure arising from abnormal PRPH2 oligomerization are manifested at the stage of disc enclosure.SIGNIFICANCE STATEMENTThe light-sensitive photoreceptor outer segment contains a stack of flattened “disc” membranes that are surrounded, or “enclosed,” by the outer segment membrane. Disc enclosure is an adaptation increasing photoreceptor light sensitivity by facilitating the diffusion of the second messenger along the outer segment axes. However, the molecular mechanisms by which photoreceptor discs enclose within the outer segment membrane remain poorly understood. We now demonstrate that oligomers of the photoreceptor-specific protein peripherin-2, or PRPH2, play an active role in this process. We further propose that defects in disc enclosure because of abnormal PRPH2 oligomerization result in major structural abnormalities of the outer segment, ultimately leading to loss of visual function and cell degeneration in PRPH2 mutant models and human patients.

Published: March 2021

BACKGROUND:
One in five pediatric patients suffers from adverse events related to hospital discharge. Current literature lacks evidence on effective interventions to improve caregiver comprehension (CC) of discharge instructions. We examined if a standardized framework for written and verbal discharge counseling was associated with increased CC of key discharge instructions after discharge from a general pediatric inpatient unit.

METHODS:
An interprofessional team created the SAFER Care framework to encourage standard, comprehensive discharge counseling. Plan-do-study-act cycles included electronic health record smartphrases, educational initiatives, data feedback, visual aids, and family outreach. Caregivers were surveyed by phone within 4 days of discharge. Our primary outcome was the proportion of caregivers correctly responding to all questions related to discharge care, comparing pre- and postintervention periods. Data were plotted on a statistical process control chart to assess the effectiveness of interventions.

RESULTS:
A total of 171 surveys were analyzed in the preintervention period, and 262 surveys were analyzed in the postintervention period. A total of 37% of caregivers correctly responded to all questions in the preintervention period, compared with 62% of caregivers in the postintervention period, meeting rules for special cause variation.

CONCLUSIONS:
Development of the SAFER Care framework and its use in written and verbal discharge counseling was associated with significantly improved CC of discharge instructions in a general pediatric inpatient unit. Further studies should be focused on expanding this to other populations, particularly limited–English-proficiency families.

Authors: TÜRER CABBAR Ayça , ŞIMŞEK Mustafa Aytek , HÜNÜK Burak , ÖZVEREN Olcay , GÜZELBURÇ Özge , DEĞERTEKIN Muzaffer 
Published: March 2021

Objective
Since many studies focused on the relationship
between mean platelet volume (MPV) and severity of
type 2 diabetes mellitus (T2DM) or investigated MPV
and coronary artery disease (CAD) mostly on acute
coronary syndrome (ACS), this study primarily focused
to investigate if MPV values have any relation with
different levels of CAD specifically in T2DM patients,
who had no previous coronary artery disease, and no
ACS history.
Materials And Methods
T2DM patients who had first coronary angiography
(CAG) between November 2019 and February
2020, and whose after night fasting blood tests
were performed before CAG were included. Two
cardiologists, blinded to the patients, evaluated
angiographies. Patients have divided into groups
accordingly; normal coronary artery (Group 1),
non-critic stenosis (Group II), and severe CAD
(Group III) according to the Gensini score. Patients’
demographics, heart rate, risk factors of CAD, and
blood test including MPV were also collected.
Results
A total of 180 patients (88 female, 92 male) were
involved in the study. There was no significant relation
between MPV and the severity of CAD in T2DM
patients (p=0.228). The mean age of the Group I group
was significantly lower than in other groups (p=0.228),
and there were significantly lower males in Group I
than other groups (p=0.0001). The triglycerides levels
were significantly low in Group I than in other groups
(p=0.021 and p=0.006).
Conclusion
MPV values were not associated with the severity
of CAD in stable patients. Older age, male gender,
higher levels of triglycerides, and initial glucose levels
were significantly related to the severity of CAD in
T2DM patients.

Jak w bibliotece Gustawa Herlinga-Grudzińskiego znalazła się partytura opery Il Prigioniero Luigiego Dallapiccoli?
Authors: Dzierżanowski Lech 
Published: March 2021

Artykuł opisuje epizod dotyczący współpracy dwóch wybitnych twórców emigracyjnych: kompozytora Romana Palestra i pisarza Gustawa Herlinga-Grudzińskiego, który o mały włos nie doprowadził do powstania wspólnego dzieła – opery opartej na opowiadaniu Grudzińskiego Wieża z muzyką Palestra. Punktem wyjścia jest fakt istnienia w bibliotece Herlinga partytury opery Luigi Dallapiccoli – Il Prigioniero. W rozwikłaniu zagadki, skąd w zbiorach pisarza znalazła się ta właśnie partytura, pomocna okazuje się korespondencja obu twórców. Po krótkiej charakterystyce perypetii życiowych i drogi twórczej obu artystów w momencie rozpoczęcia znajomości, autor przechodzi do zainteresowań operowych Palestra: przedstawia pokrótce historię niedokończonej opery Żywe kamienie, a także cytuje fragmenty jego korespondencji z różnymi pisarzami dotyczącymi poszukiwania odpowiedniego libretta operowego. Po rozpatrzeniu wielu różnych propozycji okazuje się, że najatrakcyjniejszym dla kompozytora materiałem jest opowiadanie Grudzińskiego Wieża, oczywiście po odpowiedniej adaptacji na libretto. To właśnie w tym celu, za sugestią Palestra, Herling kupuje partyturę, która do dziś zachowała się w jego bibliotece. Duży cytat z jego listu jest dowodem, jak daleko obaj twórcy zaangażowali się w potencjalną współpracę. Jednak ostatecznie do niej nie doszło. Autor opisuje perypetie tego projektu, próbując dociec, jakie ostateczne przyczyny sprawiły, że tandem twórczy Grudziński–Palester ostatecznie nie zaistniał. Wspomina też dalsze, również niezrealizowane plany operowe obu emigracyjnych twórców.
Factors Contributing to Landslide Susceptibility of the Kope Formation, Cincinnati, Ohio
Authors: Glassmeyer Michael P. , Shakoor Abdul 
Published: March 2021

ABSTRACT
The objective of this study was to evaluate the factors that contribute to the high frequency of landslides in the Kope Formation and the overlying colluvial soil present in the Cincinnati area, southwestern Ohio. The Kope Formation consists of approximately 80 percent shale inter-bedded with 20 percent limestone. The colluvium that forms from the weathering of the shale bedrock consists of a low-plasticity clay. Based on field observations, LiDAR data, and information gathered from city and county agencies, we created a landslide inventory map for the Cincinnati area, identifying 842 landslides. From the inventory map, we selected 10 landslides that included seven rotational and three translational slides for detailed investigations. Representative samples were collected from the landslide sites for determining natural water content, Atterberg limits, grain size distribution, shear strength parameters, and slake durability index. For the translational landslides, strength parameters were determined along the contact between the bedrock and the overlying colluvium. The results of the study indicate that multiple factors contribute to landslide susceptibility of the Kope Formation and the overlying colluvium, including low shear strength of the colluvial soil, development of porewater pressure within the slope, human activity such as loading the top or cutting the toe of a slope, low to very low durability of the bedrock that allows rapid disintegration of the bedrock and accumulation of colluvial soil, undercutting of the slope toe by stream water, and steepness of the slopes.
Analysis of Production Data from Communicating Multifractured Horizontal Wells Using the Dynamic Drainage Area Concept

Published: March 2021

Summary
Reduction of fracture/well spacing and increases in hydraulic fracture stimulation treatment size are popular strategies for improving hydrocarbon recovery from multifractured horizontal wells (MFHWs). However, these strategies can also increase the chance of fracture interference, which can not only negatively impact the overall production but also introduce complexities for production data analysis. A semianalytical model is therefore developed to analyze production data from two communicating MFHWs and applied to a field case.
The new semianalytical model uses the dynamic drainage area (DDA) concept and assumes three porosity regions. The three-region model is comprised of a primary hydraulic fracture (PHF), an enhanced fractured region (EFR) adjacent to the PHF, and a nonstimulated region (NSR). Assuming a well pair primarily communicates through PHFs, the equations for two communicating wells are coupled and solved simultaneously to model the fluid transfer between the wells. This method is used within a history-matching framework to estimate the communication between the wells by matching the production data.
The semianalytical model is first verified against a more rigorous, fully numerical simulation model for a range of fracture/reservoir properties. These comparisons demonstrate that there is excellent agreement between the fully numerical simulation model results and the new semianalytical model.
The semianalytical model is then employed to history-match production data from six MFHWs (drilled from two adjacent well pads) exhibiting different degrees of communication. For the purpose of history matching the data, only strong communication between pairs of wells (intrapair communication) is considered in the three-region model, and the results show good agreement with the field data.
A flexible, yet simple, semianalytical model is developed for the first time that can accurately model the communication between multiple well pairs. This approach can be used by reservoir engineers to analyze the production data from communicating MFHWs.

Abstract
The diversity of marine biomasses is a set of exploitable and renewable resources with application in several sectors. In this context, a co-culture based on three protease-producing bacterial isolates namely; Aeribacillus pallidus VP3, Lysinibacillus fusiformis C250R , and Anoxybacillus kamchatkensis M1V strains, was carried out in a medium based on the invasive blue crab Portunus segnis bio-waste. Optimization of proteases production was performed using a central composite design (CCD). The highest level of proteases production obtained was 8,809 U/mL in a medium comprising 75 g/L of Portunus segnis by-product powder (Pspp ). The recovered protein hydrolysate (P Hyd ) was found to be active towards radical scavenging power, and against angiotensin I-converting enzyme (ACE). The extraction efficiency of the blue crab chitin (BC) was achieved with a yield of 32%. Afterward, chitosan was prepared through chitin N -deacetylation with a yield of 52%, leading to an acetylation degree (AD) of 19% and solubility of 90%. The spectrum of chitin and chitosan were depicted by Fourier-transform infrared spectroscopy (FTIR). The biological value of Pspp and its obtained derivates were evidenced via accredited protocols. These data constitute a roadmap towards a circular and sustainable bio-economic strategy for a clean transformation of a recalcitrant waste to bio-based products.
