Topological properties of metal-organic frameworks
Authors: Awais Hafiz Muhammad , Jamal Muhammad , Javaid Muhammad 
Published: May 2020

Abstract
Metal-organic frameworks (MOFs) are porous materials formed by strong bonds between metal ions and organic ligands to represent very high surface area, large pore volume, excellent chemical stability and unique morphology. Work on synthesis, structures and characteristics of many MOFs shows the importance of these frameworks with versatile applications, such as energy storage devices of excellent electrode materials, gas storage, heterogeneous catalysis, environmental hazard, assessment of chemicals and sensing of different gases. A topological property or index is a numerical invariant that predicts the physicochemical properties of the chemical compounds of the underlying molecular graph or framework. Wiener (1947) created the practice of the topological indices (TI’s) in organic molecules with the reference of boiling point of paraffin. In this paper, we study the two different metal-organic frameworks with respect to the number of increasing layers with metal and organic ligands as well. We also compute the generalized Zagreb index and generalized Zagreb connection index of these frameworks. Moreover, the various indices and connection indices are obtained by using the aforesaid generalized versions. At the end, a comparison is also included between the indices and connection indices with the help of numerical values and their 3D plots.

Abstract
We report experimental observation of polarization attractors in the form of vector dissipative solitons from a carbon nanotube mode locked fiber laser. At a time scale of 14–14,000 roundtrips, the typical polarization locked vector solitons, and other appealing attractors are shown. In addition, we observe the vector dissipative solitons operated in dual-wavelength regime with central wavelength of 1533 and 1557 nm which can be related to a fixed point polarization attractor. The results unveiled complex oscillatory behavior of dissipative solitons in the polarization domain which may help understand laser physics, nonlinear optics. The demonstrated work may underpin a new type of high energy laser source leading to possible applications in nanoparticle manipulation, micromachining, spectroscopy etc.
Dynamic tuning of enhanced intrinsic circular dichroism in plasmonic stereo-metamolecule array with surface lattice resonance

Published: May 2020

Abstract
Enhancing the circular dichroism signals of chiral plasmonic nanostructures is vital for realizing miniaturized functional chiroptical devices, such as ultrathin wave plates and high-performance chiral biosensors. Rationally assembling individual plasmonic metamolecules into coupled nanoclusters or periodic arrays provides an extra degree of freedom to effectively manipulate and leverage the intrinsic circular dichroism of the constituent structures. Here, we show that sophisticated manipulation over the geometric parameters of a plasmonic stereo-metamolecule array enables selective excitation of its surface lattice resonance mode either by left- or right-handed circularly polarized incidence through diffraction coupling, which can significantly amplify the differential absorption and hence the intrinsic circular dichroism. In particular, since the diffraction coupling requires no index-matching condition and its handedness can be switched by manipulating the refractive index of either the superstrate or the substrate, it is therefore possible to achieve dynamic tuning and active control of the intrinsic circular dichroism response without the need of modifying structure parameters. Our proposed system provides a versatile platform for ultrasensitive chiral plasmonics biosensing and light field manipulation.
We Make Up the Rules as We Go Along: Improvisation as an Essential Aspect of Human Practices?
Authors: Bertinetto Alessandro , Bertram Georg W. 
Published: May 2020

Abstract
The article presents the conceptual groundwork for an understanding of the essentially improvisational dimension of human rationality. It aims to clarify how we should think about important concepts pertinent to central aspects of human practices, namely, the concepts of improvisation, normativity, habit, and freedom. In order to understand the sense in which human practices are essentially improvisational, it is first necessary to criticize misconceptions about improvisation as lack of preparation and creatio ex nihilo. Second, it is necessary to solve the theoretical problems that derive from misunderstandings concerning the notions of normativity, habit, and freedom – misunderstandings that revolve around the idea that rationality is a form that is developed out of itself and thus works in a way similar to algorithms. One can only make sense of normativity, habit, and freedom if one understands that they all involve conflictual relationships with the world and with others, which in turn enables one to adequately take into account their constitutive connection to improvisation, properly understood. In outlining these conceptual connections, we want to prepare the foundations for an explanation of rational practices as improvisational practices. The article concludes by stating that human rational life is improvisatory because the conditions of human practice arise out of practice itself.
Growth-Dependent Activation of Protein Kinases Suggests a Mechanism for Measuring Cell Growth

Published: May 2020

AbstractProgression through the cell cycle occurs only when sufficient growth has occurred, which indicates that cells measure growth. Analysis of signals associated with...In all cells, progression through the cell cycle occurs only when sufficient growth has occurred. Thus, cells must translate growth into a proportional signal that can be used to measure and transmit information about growth. Previous genetic studies in budding yeast suggested that related kinases called Gin4 and Hsl1 could function in mechanisms that measure bud growth; however, interpretation of the data was complicated by the use of gene deletions that cause complex terminal phenotypes. Here, we used the first conditional alleles of Gin4 and Hsl1 to more precisely define their functions. We show that excessive bud growth during a prolonged mitotic delay is an immediate consequence of inactivating Gin4 and Hsl1. Thus, acute loss of Gin4 and Hsl1 causes cells to behave as though they cannot detect that bud growth has occurred. We further show that Gin4 and Hsl1 undergo gradual hyperphosphorylation during bud growth that is dependent upon growth and correlated with the extent of growth. Moreover, gradual hyperphosphorylation of Gin4 during bud growth requires binding to anionic phospholipids that are delivered to the growing bud. While alternative models are possible, the data suggest that signaling lipids delivered to the growing bud generate a growth-dependent signal that could be used to measure bud growth.

Exploring the Benefit of Yoga Programs in Carceral Settings
Authors: Rousseau Danielle , Horton Carol 
Published: May 2020

Abstract
This article presents a perspective on the value of yoga and mindfulness programming in carceral settings. The authors explore this topic through interviews with two formerly incarcerated people who participated in yoga programming while incarcerated and who went on to become yoga instructors themselves. Also examined are the potential effects of yoga programming for people who are incarcerated, for those working within carceral settings, and on carceral environments generally. We share recommendations for implementing yoga programming in carceral institutions and discuss policy implications. The stories of both interviewees reflect the value and potential positive effects of yoga programming within criminal justice settings and suggest the need for sustained programming and ongoing empirical evaluation.

Background: recently, it has been proved that copolymers with dextran cores and grafted polyacrylamide are effective in photodynamic and chemotherapy. However, further research is needed to define correct dosage and to assess the risks. Thus, animal studies are becoming more relevant to determine the effect of the treatment of such drug nano-systems on female reproductive function in particular.Methods: a technique for estimation of pre- and post-implantation death rates, in vitro meotic maturation of oocytes, double fluorescent vital assay and statistical analysis were used. The effects of a one-time treatment of different doses of dextran-polyacrylamide matrices and silver (Ag)-nanoparticles-dextran-polyacrylamide (AgNPs-D-PAA) on reproductive function, namely on 1) the number of oocytes isolated from one ovary and the meiotic maturation of such oocytes in vitro; 2) the indicators of cell viability of the cells of follicular environment of oocytes (FEO) and the cells of inguinal lymph nodes (ILN); 3) the pre- and post-implantation mortality rates and the number of live newborns (pups) were investigated in female mice.Results: no significant changes in the number of oocytes isolated from one ovary and meiotic maturation of such ovarian oocytes in vitro, the number of living cells of follicular environment of oocytes and the number of such cells with morphological signs of apoptosis and necrosis, pre- and post-implantation mortality rates of embryos and the number of live newborns (pups) have been established under conditions of one-time treatment with dextran-polyacrylamide at doses of 0.39 mg/kg and 3.90 mg/kg and Ag-nanoparticles-dextran-polyacrylamide at doses of 0.20 mg/kg and 2.00 mg/kg.Conclusions: branched polymer systems (dextran-polyacrylamide (D-PAA) polymer matrices) are promising materials for use in next-generation medicine.

The Relationship Between Quadriceps Muscle Atrophy and Proprioception Function in Knee Osteoarthritis Patients
Authors: Susanti Ayu , Wardhani Rr. Indrayuni Lukitra , Pawana I Putu Alit 
Published: May 2020

Background: Osteoarthritis of the knee (OA) patients can experience impaired proprioceptive function which causes instability, balance disorder and limited activity. Further analysis is needed to detect changes that occur. There are two methods to evaluate the speed and angle of a particular motion as an analysis of the function of proprioception, Time to Detect Passive Movements (TTDPM) and Joint Position Sense (JPS).Aim: To analyze the relationship between quadriceps muscle atrophy with proprioception in knee osteoarthritis patients.Methods: The design of this research is cross sectional analysis done in Dr. Soetomo General Hospital Surabaya, Indonesia. There were 25 knee OA patients (2 men and 23 women) with each subject had proprioception (JPS and TTDPM) function measured using isokinetics dynamometer on both sides of the knee.Results: This study shows the atrophic side had greater pain intensity and greater disturbance of proprioception. In addition, there were significant differences in JPS measurements at angle of 30⁰, and 60⁰ and TTDPM (p <0.05). No difference obtained at 45⁰ measurements angle.Conclusion: In this study, there was no association between quadriceps atrophy and function of proprioception in knee osteoarthritis patients. This was due to a number of confounding factors that cannot be controlled such as duration, difference in pain intensity, OA severity, physical activity before measurement, and fatigue which can affect proprioception function and bring misinterpretation on measurements.
Fixator-Assisted Nailing for Managing Slipped Capital Femoral Epiphysis Sequelae: A Novel Technique
Authors: Hashem Majdi , Alatassi Raheef 
Published: May 2020

Case:
An 18-year-old man with a slipped capital femoral epiphysis treated within in situ screw fixation 5 years earlier presented to our clinic with hip pain, limping, and limited range of motion (ROM) of the left hip. Fixator-assisted nailing (FAN) accompanied by double femoral osteotomies was performed to treat the proximal femoral deformity. At follow-up, the patient had regained full ROM and acceptable alignment of the left lower limb.

Conclusion:
The FAN approach effectively manages proximal femoral deformities in select patients. It requires careful analysis of the deformity, meticulous preoperative planning, and surgeons familiar with both intramedullary nailing and external fixation techniques.
Intra-articular Extraskeletal EWSR1-Negative NR4A3-Positive Myxoid Chondrosarcoma
Authors: Lal Divakar N. , El-Zammar Ola , Naous Rana , Damron Timothy A. 
Published: May 2020

Case:Extraskeletal myxoid chondrosarcomas (EMCs) are rare soft-tissue malignancies. Intra-articular occurrence is even more rare. To our knowledge, this case is one of only 2 reported intra-articular EMC cases of the knee free of local recurrence and/or amputation at follow-up. This case is also distinctive for being fluorescence in-situ hybridization–negative for the typical EMC-balanced translocation t(9;22) which fusesEWSR1withNR4A3, harboring instead a variant translocation resulting in fusion ofNR4A3with a less common gene fusion partner.Conclusion:This is a unique case of intra-articular EMC of the knee with a rare molecular fingerprint and an unusually positive outcome.
Rapid Neurologic Deterioration due to an Enlarging Thoracic Spine Synovial Cyst
Authors: Lambrechts Mark J. , Goldstein Christina L. 
Published: May 2020

Case:
We present the case of a 69-year-old man arriving to our clinic after a previous outside hospital recommendation of L1-S1 fusion due to degenerative scoliosis. A thoracic spine synovial cyst was identified through magnetic resonance imaging. The patient had rapid progression of his neurologic deficit due to cyst enlargement. We elected to perform cyst decompression and instrumented fusion of the involved thoracic segment. The patient rapidly regained full neurologic function. After the one-year follow-up, he remained asymptomatic with no progression of thoracolumbar degeneration.

Conclusions:
Thoracic spine synovial facet cysts are uncommonly encountered. Decompression alone or decompression and fusion are both viable treatment options depending on the surgeon's assessment of spine stability after decompression. This diagnosis should be considered in patients presenting with unilateral lower extremity upper motor neuron findings.
The origin and significance of convolute lamination and pseudonodules in an ancient deep-marine turbidite system: From deposition to diagenesis
Authors: Al-Mufti Omar N. , Arnott R. William C. 
Published: May 2020

ABSTRACTSoft-sediment deformation structures, like convolute lamination and pseudonodules, are common in deep-marine turbidites, but details of their origin and timing of formation remain a source of debate. Deep-marine basin-floor deposits of the Neoproterozoic Upper Kaza Group (Windermere Supergroup) crop out superbly in the Castle Creek study area and provide an ideal laboratory to investigate these aspects in convolute-laminated pseudonodules, and also how that deformation influenced later diagenesis. Pseudonodules consist of well-sorted, matrix-poor, upper medium- to coarse-grained, planar-stratified or cross-stratified sandstone that are underlain and overlain by comparatively more poorly sorted, matrix-rich, graded sandstone of similar grain size. Deposition of the stratified pseudonodules is interpreted to have occurred during the same event that deposited the graded sandstone, albeit during a period of general transport bypass, whereby isolated, shallow, seafloor depressions became filled with well-sorted, stratified sand. As stratified sand accumulated the depressions slowly subsided until a critical thickness had built up and exceeded the load-bearing capacity of the substrate composed of graded sand. This destabilized the surface separating the two layers and resulted in the stratified unit foundering, and in some cases becoming completely enveloped by, the upward-displaced lower-density substrate. Surprisingly, despite the deformed macroscopic character of the stratified sediment, primary grain fabric, including intergranular porosity up to 40%, was preserved and influenced early diagenesis, which, owing to dispersed phosphate cement and depleted carbon isotope composition of the pervasive carbonate cement, would have begun very near the sediment–water interface. Importantly also, pseudonodules are common in basin-floor deposits but comparatively rare in continental-slope strata. Expanding flow conditions over the basin floor would have promoted grain settling, and in turn development of a more stably (density) stratified flow structure. Ultimately this resulted in higher local rates of sedimentation on the basin floor and the accumulation of a substrate more prone to later liquidization.

Abstract
Background: This concept analysis aimed to clarify the meaning of “children with complex health conditions” and endorse a definition to inform future research, policy, and practice. Methods: Using Walker and Avant’s (2011)’s approach, we refined the search strategy with input from our team, including family representatives. We reviewed the published and grey literature. We also interviewed 84 health, social, and educational stakeholders involved in the care of children with complex health conditions about their use/understanding of the concept. Results: We provided model, borderline, related, and contrary cases for clarification purposes. We identified defining attributes that nuance the concept: (1) conditions and needs’ breadth; (2) uniqueness of each child/condition; (3) varying extent of severity over time; 4) developmental age; and (5) uniqueness of each family/context. Antecedents were chronic physical, mental, developmental, and/or behavioural condition(s). There were individual, family, and system consequences, including fragmented services. Conclusions: Building on previous definitions, we proposed an iteration that acknowledges the conditions’ changing trajectories as involving one or more chronic condition(s), regardless of type(s), whose trajectories can change over time, requiring services across sectors/settings, oftentimes resulting in a lower quality of life. A strength of this paper is the integration of the stakeholders’/family’s voices into the development of the definition.
