Adapted Metrics for a Modified Coulomb/Newton’s Potential

Modified Theories of Gravity include spin dependence in General Relativity, to account for additional sources of gravity instead of dark matter/energy approach. The spin-spin interaction is already included in the effective nuclear force potential, and theoretical considerations and experimental evidence hint to the hypothesis that Gravity originates from such an interaction, under an averaging process over spin directions. This invites to continue the line of theory initiated by Einstein and Cartan, based on tetrads and spin effects modeled by connections with torsion. As a first step in this direction, the article considers a new modified Coulomb/Newton Law accounting for the spin-spin interaction. The physical potential is geometrized through specific affine connections and specific semi-Riemannian metrics, canonically associated to it, acting on a manifold or at the level of its tangent bundle. Freely falling particles in these “toy Universes” are determined, showing an interesting behavior and unexpected patterns.

Randomized control trial of a culturally adapted behavioral activation therapy for Muslim patients with depression in Pakistan

BACKGROUND Behavioral activation therapy(BA)is as effective as cognitive behavior therapy(CBT)in treating depression and can be delivered by practitioners with much less psychological training,making it particularly suitable for low resource settings.BA that is culturally adapted for Muslims(BA-M)is a culturally adapted form of BA that has been found acceptable and feasible for Muslims with depression in the United Kingdom and Turkey;however,this is the first time that its efficacy has been determined through a definitive randomized controlled trial.AIM To compare the effectiveness of BA-M with CBT for Muslim patients with depression in Pakistan.METHODS One hundred and eight patients were randomized 1:1 to treatment arms in a parallel-group randomized controlled trial in hospital or community sites in Lahore,Pakistan.Recruitment followed self-referral or referrals from clinicians,consultants or relevant professionals at each site.Four measures were recorded by blinded assessors:The patient health questionnaire-9(PHQ-9);the BA for depression scale short form(BADS-SF);symptom checklist-revised and the World Health Organization Quality-of-Life Brief Scale.All measures were recorded at baseline and post treatment;PHQ-9 and BADS-SF were also recorded at each session and at three month follow up.The primary analysis was to regress the PHQ-9 score after therapy upon the PHQ-9 score before therapy(baseline)and the type of therapy given,that is,analysis of covariance.In addition,analysis using PHQ-9 scores collected at each therapy session was employed in a 2-level regression model.RESULTS Patients in the BA-M arm experienced greater improvement in PHQ-9 score of 1.95 units compared to the CBT arm after adjusting for baseline values(P=0.006)The key reason behind this improvement was that patients were retained in therapy longer under BA-M,in which patients were retained for an average 0.75 sessions more than CBT patients(P=0.013).Patients also showed significant differences on physical(P<0.001),psychological(P=0.004)and social(P=0.047)domains of Quality of Life(QoL)at post treatment level,indicating an increased QoL in the BA-M group as compared to the treatment as usual group.Some baseline differences were noted in both groups for BA scores and two domains of QoL scale:Physical and environment,which might have influenced the results,though the BA-M group showed more improvement at completion of therapy.CONCLUSION Results proved the efficacy of BA-M in reducing symptoms for depressed patients in Pakistan,indicating BA-M is a promising treatment modality for depression in future,particularly in low resource settings.

Preliminary Results of Dementia Prevalence among Elderly People at Home by Cognitive Disorder Adapted Test of Niamey (Niger)

Introduction: Neurocognitive disorders are frequent with aging and are often seen at advancing stages in our context. It is really difficult to evaluate rapidly Nigerien elderly persons according to tools available on cognitive status while there is a great number of uneducated elderly people who suffer from cognitive deficiency. The purpose was to determine neurocognitive disorders prevalence in uneducated groups and Muslim elderly people by using the cognitive disorder examination (Codex) test adopted in the population living at home in Niamey (Niger). Materials and Methods: These are the results of a preliminary prospective study with simple three (3) random sampling concerning elderly people aged 60 and over living at home in whom the codex test adapted to Niamey was administered in uneducated Muslim elderly people for a total duration of four (4) minutes. This screen-adapted test should be completed by the mini-mental test of Senegal which is adapted globally to uneducated people in hospitals. The basic Codex test was developed in France for educated people, so we used this basic test in our educated people in the same study. Results: A total of 198 patients had been collected, of which 51.5% were female with an average age of 68 years with extremes of 60 to 84 years. 40 were educated. Among educated persons, 62.5% had a very low probability of dementia and 5% had a very high probability of dementia in the first step of the Codex. In the second step, 12.5% had a low probability of dementia and 20% had a high probability in the same group, while 51.3% had a very low probability of dementia and 21.3% had a very high probability of dementia in the first step of CODEX in uneducated elderly. In the second step in the same group, 12.6% had a low probability and 14.5% had a high probability of dementia. Conclusion: The adapted codex test of Niamey is simple and could be rapidly used to screen dementia among uneducated elderly Muslim prayers, and then could confirm it by complementary cognitive status test validated in the same population. However, it should be confirmed by using a large sample.

Heterosis in locally adapted sorghum genotypes and potential of hybrids for increased productivity in contrasting environments in Ethiopia

Increased productivity in sorghum has been achieved in the developed world using hybrids.Despite their yield advantage,introduced hybrids have not been adopted in Ethiopia due to the lack of adaptive traits,their short plant stature and small grain size.This study was conducted to investigate hybrid performance and the magnitude of heterosis of locally adapted genotypes in addition to introduced hybrids in three contrasting environments in Ethiopia.In total,139 hybrids,derived from introduced seed parents crossed with locally adapted genotypes and introduced R lines,were evaluated.Overall,the hybrids matured earlier than the adapted parents,but had higher grain yield,plant height,grain number and grain weight in all environments.The lowland adapted hybrids displayed a mean better parent heterosis(BPH) of19%,equating to 1160 kg ha-1and a 29% mean increase in grain yield,in addition to increased plant height and grain weight,in comparison to the hybrids derived from the introduced R lines.The mean BPH for grain yield for the highland adapted hybrids was 16% in the highland and 52%in the intermediate environment equating to 698 kg ha-1and 2031 kg ha-1,respectively,in addition to increased grain weight.The magnitude of heterosis observed for each hybrid group was related to the genetic distance between the parental lines.The majority of hybrids also showed superiority over the standard check varieties.In general,hybrids from locally adapted genotypes were superior in grain yield,plant height and grain weight compared to the high parents and introduced hybrids indicating the potential for hybrids to increase productivity while addressing farmers' required traits.

Stealth Adapted Viruses: A Bridge between Molecular Virology and Clinical Psychiatry

Cytopathic “stealth-adapted” viruses bypass the cellular immune defense mechanisms because of molecular deletion or mutation of critical antigen coding genes. They, therefore, do not provoke the inflammatory reaction typical of infections with the conventional viruses from which stealth adapted viruses are derived. Stealth adapted viruses establish persistent, systemic virus infections, which commonly involve the brain. The brain damage can cause major mood and cognitive disorders, fatigue, seizures and various manifestations of an impaired autonomic nervous system. Symptoms can also result from: 1) induced autoimmunity, 2) antibody formation against virus antigens, 3) virus-induced cellular damage to non-brain tissues and 4) induced heightened overall immune reactivity, such that normally unrecognized components of the virus begin to become targeted by the cellular immune system. This last mechanism is relevant to the reported neurological and psychiatric adverse effects of vaccination in certain individuals. It is also appropriate to consider the infectious component of stealth adapted virus infections since family members and others may be at risk for becoming infected.

The results showed that, of the 7 low temperature-adapted(LTA) strains studied, strain E, F and D gave the highest titer in BSC-1 cell culture. This culture system was proved to be suitable for the study of the characteristic of temperature mutants of HAV.

Breathing adapted radiation therapy for leukemia relapse in the breast: A case report

BACKGROUND Infiltration of the breast by leukemic cells is uncommon but may manifest as an oncological emergency requiring prompt management.Extramedullary relapse of T-cell acute lymphoblastic leukemia(T-ALL)within the breast is exceedingly rare and there is paucity of data in the literature regarding this entity.No consensus exists on management of isolated extramedullary breast relapses of T-ALL.Herein,we report a case of isolated extramedullary breast relapse of T-ALL treated with breathing adapted radiation therapy(BART)using the active breathing control(ABC)system.CASE SUMMARY The patient was a 33-year-old female with diagnosis of T-ALL.She received intensive systemic chemotherapy that resulted in complete remission of her disease,and then underwent allogeneic hematopoietic stem cell transplantation.After a 15 mo period without symptoms and signs of progression,the patient presented with palpable masses in both breasts.She complained from severe pain and swelling of the breasts.Imaging workup showed bilateral breast lesions,and diagnosis of breast infiltration by leukemic cells was confirmed after immunohistopathological evaluation.The patient suffering from severe pain,discomfort,and swelling of both breasts due to leukemic infiltration was referred to the Radiation Oncology Department for symptomatic palliation.Whole breast irradiation was delivered to both breasts of the patient with BART using the ABC system.The patient had complete resolution of her symptoms after treatment with BART.CONCLUSION BART with the ABC system resulted in complete resolution of the patient’s symptoms due to leukemic infiltration of both breasts with T-ALL.This contemporary treatment technique should be preferred for radiotherapeutic management of patients with leukemic infiltration of the breasts to achieve effective symptomatic palliation.

Splitting of Gaussian Models via Adapted BML Method Pertaining to Cry-Based Diagnostic System

In this paper,we make use of the boosting method to introduce a new learning algorithm for Gaussian Mixture Models (GMMs) called adapted Boosted Mixture Learning (BML). The method possesses the ability to rectify the existing problems in other conventional techniques for estimating the GMM parameters, due in part to a new mixing-up strategy to increase the number of Gaussian components. The discriminative splitting idea is employed for Gaussian mixture densities followed by learning via the introduced method. Then, the GMM classifier was applied to distinguish between healthy infants and those that present a selected set of medical conditions. Each group includes both full-term and premature infants. Cry-pattern for each pathological condition is created by using the adapted BML method and 13-dimensional Mel-Frequency Cepstral Coefficients (MFCCs) feature vector. The test results demonstrate that the introduced method for training GMMs has a better performance than the traditional method based upon random splitting and EM-based re-estimation as a reference system in multi-pathological classification task.

Realization of Orthogonal Wavelets Adapted to Fabric Texture for Defect Detection

The wavelet adapted to the fabric texture can be developed from the orthogonal and normal series which are selected randomly by means of Monte Carlo method and op timized by adding certain constraint conditions.Then the fabric image can be decomposed into the subimages by the adaptive wavelet transform and the horizontal and vertical texture information will be perfectly contained in the subimages. Therefore this method can be effectively used for the automatic inspection of the fabric defects.

Significantly improved oxidation of bio-based furans into furan carboxylic acids using substrate-adapted whole cells

Furan carboxylic acids are important building blocks in polymer and fine chemical industries. In this work, a simple substrate adaptation strategy was applied to improve the catalytic performances of Comamonas testosteroni SC1588 cells for the synthesis of various furan carboxylic acids. It was found that biocatalytic synthesis of 5-hydroxymethyl-2-furancarboxylic acid(HMFCA) was substantially promoted by adding histidine and increasing cell concentrations. HMFCA was produced in a quantitative yield from200 m M HMF in 24 h. Besides, the HMFCA yields of 71%–81% were achieved with the substrate concentrations up to 250–300 m M. It was firstly found that 4-tert-butylcatechol(TBC), as the stabilizer present in HMF, exerted a significantly detrimental effect on whole-cell catalytic synthesis of HMFCA at high substrate concentrations(more than 130 m M). In addition, a variety of furan carboxylic acids such as2-furoic acid, 5-methyl-2-furancarboxylic acid and 5-methoxymethyl-2-furancarboxylic acid were synthesized with the yields up to 98%.

Dear Editor,As the COVID-19 epidemic proceeds,new variants of SARS-CoV-2 continue to emerge.^(1)Particularly the B.1.1.529(Omicron)variant emerged and spread globally,surpassing the previously dominant B.1.617.2(Delta)variant.Moreover,the original Omicron variant continued to mutate into numerous Omicron sublineages.Nonetheless,the infectious and immune characteristics of newly-emerged Omicron sublineages that have evolved to adapt to the host remain unclear.

Beyond familial risk: deriving risk-adapted starting ages of screening among people with a family history of colorectal cancer

Dear Editor,Colorectal cancer(CRC)is the third most common cancer globally[1],even though a large proportion of those cancers would be preventable by screening.Among those with a family history(FH)of CRC,it is commonly recommended to start screening at younger ages,e.g.,at age 40 or 10 years younger than the age at diagnosis of the youngest affected first-degree relative[2–5].Even within the group of those with a FH,risk of CRC is not homogeneous and depends on factors such as the number of affected relatives and the age at which the relatives were diagnosed with CRC[6,7],lifestyles,and genetic background profiles.However,these metrics except genetic factors may change over lifetime,which limits their use for defining starting ages of screening.The aim of this study was to evaluate whether a polygenic risk score(PRS),which combines information from CRC-related risk variants[8]and genetically determined sex(2 constant and established CRC risk factors),could effectively contribute to enhanced risk stratification.We also aimed to determine if it could assist in defining risk-adapted starting ages for CRC screening,even in individuals with a FH of CRC.The assessment was performed using the wellestablished metric of risk advancement periods(RAPs)[9],which measures the impact of an exposure on the relation of age to disease.

Reinforcement learning(RL) has roots in dynamic programming and it is called adaptive/approximate dynamic programming(ADP) within the control community. This paper reviews recent developments in ADP along with RL and its applications to various advanced control fields. First, the background of the development of ADP is described, emphasizing the significance of regulation and tracking control problems. Some effective offline and online algorithms for ADP/adaptive critic control are displayed, where the main results towards discrete-time systems and continuous-time systems are surveyed, respectively.Then, the research progress on adaptive critic control based on the event-triggered framework and under uncertain environment is discussed, respectively, where event-based design, robust stabilization, and game design are reviewed. Moreover, the extensions of ADP for addressing control problems under complex environment attract enormous attention. The ADP architecture is revisited under the perspective of data-driven and RL frameworks,showing how they promote ADP formulation significantly.Finally, several typical control applications with respect to RL and ADP are summarized, particularly in the fields of wastewater treatment processes and power systems, followed by some general prospects for future research. Overall, the comprehensive survey on ADP and RL for advanced control applications has d emonstrated its remarkable potential within the artificial intelligence era. In addition, it also plays a vital role in promoting environmental protection and industrial intelligence.

Ground-layer Adaptive Optics for the 2.5 m Wide-field and High-resolution Solar Telescope

The 2.5 m wide-field and high-resolution solar telescope(WeHoST)is currently under developing for solar observations.WeHoST aims to achieve high-resolution observations over a super-wide field of view(FOV)of5′×5′,and a desired resolution of 0.3″.To meet the scientific requirements of WeHoST,the ground-layer adaptive optics(GLAO)with a specially designed wave front sensing system is as the primary consideration.We introduce the GLAO configuration,particularly the wave front sensing scheme.Utilizing analytic method,we simulate the performance of both classical AO and GLAO systems,optimize the wave front sensing system,and evaluate GLAO performance in terms of PSF uniformity and correction improvement across whole FOV.The results indicate that,the classical AO will achieve diffraction-limited resolution;the suggested GLAO configuration will uniformly improve the seeing across the full 5′×5′FOV,reducing the FWHM across the axis FOV to less than0.3″(λ≥705 nm,r0≥11 cm),which is more than two times improvement.The specially designed wave front sensor schedule offers new potential for WeHoST’s GLAO,particularly the multi-FOV GLAO and the flexibility to select the detected area.These capabilities will significantly enhance the scientific output of the telescope.
